Feature request: custom indentation setting

[rvnkcode]

Have you searched existing Github issues to see if someone has already requested this feature? Yes

Is your feature request related to a problem? Please describe. It would be nice to be able to customize the indentation settings when formatting code. Like the use of spaces/tabs or 2/4 spaces.

Describe the solution you'd like Add a formatting menu to the settings so users can set whether to use spaces or tabs when formatting, and how many spaces to use. It would be great to be able to set it per programming language.

Describe alternatives you've considered Change the indentation setting for JS/TS/Markdown/JSON to 2 spaces.
