CLI: Add "doctor" command

[yannbf]

Relates to #23033

What I did

This PR adds a new command to the storybook CLI: storybook doctor. It's heavily based on the automigrations, in fact it takes two checks from the automigrations so they can be ran at any time, detached from the automigration command.

This will serve as a way to tell users to check their overall project health, such as:

• a project contains mismatching storybook versions
• a project contains duplicated dependencies
• a project contains addons which are not compatible

Here's an example of a single report:

Another one, when versions mismatch:

Here's an example with multiple reports:

When everything is good:

Just like the automigrations, the doctor command also generates a log file (only if there are reports) so users can send to us for support.

How to test

1. Run a sandbox for template, e.g. yarn task --task sandbox --start-from auto --template react-vite/default-ts
2. Make it wrong in either ways presented above
3. Run code/lib/cli/bin/index.js doctor from the sandbox directory

This needs a bit more love! Would love if someone reviewed it thoroughly and we worked on it a little more before we merge this.
