BREAKING: rewrite the dired module based on dirvish

- Deprecate `+ranger` flag, use dirvish by default

  See: alexluigit/dirvish#34

- Bump the package version for diredfl and dirvish
- Reimplement `+icons`, deprecate package all-the-icons-dired

  all-the-icons-dired is very slow on large directories,
  while dirvish render icons lazily.

- Use `vc-state` from dirvish, remove diff-hl-dired-mode

  1. diff-hl-dired-mode doesn't index the entries in subtrees.
  2. It freezes Emacs on big repos, while dirvish does this asynchronously in
  external process and update the UI in an nonblocking fashion.

- Use `git-msg` from dirvish, deprecate package dired-git-info

  Same reasons as in diff-hl-dired-mode.

- Use utilities in dirvish-yank.el, deprecate package dired-rsync

  `dirvish-yank` has inbuilt support for rsync.

- Use dirvish-fd, deprecate package fd-dired

  `dirvish-fd` is way powerful.

- Remove the gnuls check on remote hosts

  dirvish checks gnu ls availability for each remote host.

- Set `dired-hide-details-hide-symlink-targets` to t (default)

  We have symlink target showing on the modeline

- Add a few sensible keybindings

 * Description :unfold:
-This module provides reasonable defaults and augmentations for dired.
+This module provides reasonable defaults and augmentations for [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][Dired]], the
+inbuilt file manager for Emacs.  The extra features are mostly introduced by the
+Dired enhancement package [[https://github.com/alexluigit/dirvish][Dirvish]].

 ** Module flags
 - +icons ::
   Enables the display of fancy icons depending on file types in dired buffers.
-- +ranger ::
-  Enables dired to be more like [[https://github.com/ranger/ranger][ranger]].
+- +dirvish ::
+  Apply some stylistic defaults to the Dired buffer.
+  + Show file size at right fringe
+  + Collapse directories with only one entry in it automatically.
+  + Use prettified header line and mode line
+  + Hide file details information by default
+  + Enable line highlighting, hide the cursor

+
+* Usage
+** Global bindings
+You can access Dired/Dirvish by opening a directory entry in commands like
+~find-file (SPC f f)~. Or you can create a Dired buffer directly with these
+keybindings.
+
+| Keybind                      | Description                        |
+|------------------------------+------------------------------------|
+| [[kbd:][SPC f d]]                      | Find directory with dired          |
+| [[kbd:][SPC o -]]                      | Jump to current directory in dired |
+
+These commands are available but not bound to any keys.
+
+| Command          | Description                    |
+|------------------+--------------------------------|
+| [[kbd:][M-x dirvish]]      | Open dired with preview        |
+| [[kbd:][M-x dirvish-dwim]] | Dirvish with smart layout      |
+| [[kbd:][M-x dirvish-fd]]   | Search files in dired using fd |
+| [[kbd:][M-x dirvish-side]] | Open project sidebar           |
+
+** Dired bindings
+*** Basics
+Note that these are Emacs bindings, if you have enabled ~(evil
++everywhere)~, you should consult =evil-collection= for the actual bindings.
+
+| Keybind | Description                               |
+|---------+-------------------------------------------|
+| [[kbd:][n]]       | Move down a line                          |
+| [[kbd:][p]]       | Move up a line                            |
+| [[kbd:][e]]       | Visit the file or directory on this line  |
+| [[kbd:][(]]       | Toggle visibility of detailed information |
+| [[kbd:][q]]       | Exit dired buffer                         |
+| [[kbd:][^]]       | Go Up a directory                         |

+| [[kbd:][D]]       | Delete a file                             |
+| ...     | ...                                       |

+This is only a very small sample of dired keybindings, just for you to get a
+sense of Dired.  Other basic keybindings can be found on the official [[https://www.gnu.org/software/emacs/refcards/pdf/dired-ref.pdf][Dired
+reference card]].
+
+*** Extras
+You don't have to memorize all of Dired bindings because this module provided a
+lot of easy-to-read menus such as ~dirvish-mark-menu~ (powered by =transient.el=)
+for you to find the suitable command in a specific context.  All of these
+(sub-)menus are included in ~dirvish-dispatch (?)~, the main help menu.  Some
+extremely useful ones are bound to a separate keys as well.

+Use the following syntax to configure the entries displayed in
+~dirvish-quick-access~ command.
