add ignoreSubmodules option

[Ben Curtis (Fmstrat)]

This PR fixes #88715
(now that it has for when it reaches 20 up-votes)

Purpose: Adds a setting to ignore modifications to submodules in the file tree so that large monorepos don't show numerous modifications.

Testing:

• Open VSCode to a repo with submodules
• Go to settings and find the "Ignore Submodules" setting
• Check and uncheck the box to watch the 'M' convert to an 'S'

Hey all,

Looks like I'm failing tests in https://dev.azure.com/vscode/VSCode/_build/results?buildId=35951&view=logs&j=0da5d1d9-276d-5173-c4c4-9d4d4ed14fdb&t=47d55512-6160-5b27-084a-e3e9b13d4d4b

.. but I don't see any reason why? Perhaps there is something else in the branch causing that error?

EDIT: I should note, this passed tests when the PR started

No worries, these were broken in master, not related to your changes.

Thanks João Moreno (@joaomoreno), Any idea when this could be merged in?

[João Moreno (joaomoreno)]

Thanks! 🍻

[Ben Curtis (Fmstrat)]

Oh I see this hit a merge, thanks! Any idea when it will be pushed into the VSCode Repo (Ubuntu)?

EDIT: And now I realize the issue it's tied to is in a milestone https://github.com/microsoft/vscode/milestone/136
