[FR] Master issue for Code Block improvements

[Xazin]

Description

Improvements:

• [ ] Enable hide line numbers
• [ ] Show the language that is guessed by the "Auto" option
• [ ] Allow changing the indentation level
• [ ] Bracket completion
• [ ] Collapse code block
• [ ] Auto indentation improvement after opening brakcet

Impact

More control over the behavior of the code block depending on the usage and language.

Additional Context

Code block is over at https://github.com/AppFlowy-IO/AppFlowy-plugins

Much of the implementations can be done in the main repository, but there is a need for some enablers in the plugins repository.

I did some basic Bracket Completion using Character Shortcut Events: https://github.com/MayurSMahajan/code_block/blob/main/lib/src/utils/shortcuts/character_shortcuts/braces_shortcut.dart

Can it support automatic line wrapping switching?

Can it support automatic line wrapping switching?

Yes, I need to find a suitable implementation for line number replacement when wrapping lines though.

I'm not sure if I described it clearly, I need a function like this
