Update bin.rst and add bin to doctest

[ahkcs]

Description

Update the doctest for bin.rst file
Removed floating point for numeric span

[ykmr1224]

Not critical, but these examples might be a bit confusing since it shows duplicate age bins. It is better showing other field to indicate age is just showing the bin for each record.

[ahkcs]

Updated some tests to use fields command

Let's reuse existing ones if possible. I think bank can be replaced with accounts, at least. Not sure if we have json with timestamp.

[vamsimanohar]

+1 lets reuse unless necessary.

[ahkcs]

We currently don't have json with timestamp so I kept time_test.json, removed bank.json

[ykmr1224]

Let's put items in alphabetical order to easily identify duplicate record.

#4379 is to moving all doctest to calcite. But I can rebase that one. Let's merge this first.

The backport to 2.19-dev failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/sql/backport-2.19-dev 2.19-dev
# Navigate to the new working tree
pushd ../.worktrees/sql/backport-2.19-dev
# Create a new branch
git switch --create backport/backport-4384-to-2.19-dev
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 877e6d586287171019b4390231accd7f2a887c2a
# Push it to GitHub
git push --set-upstream origin backport/backport-4384-to-2.19-dev
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/sql/backport-2.19-dev

Then, create a pull request where the base branch is 2.19-dev and the compare/head branch is backport/backport-4384-to-2.19-dev.
