Visual Studio Project Properties shows C# warning levels in dropdown that don't apply to F# at all

[abelbraaksma]

The available options dropdown in VS 2022 and VS 2022 Preview lists them in relation to C#, and shows too many of them:

Repro steps

1. Open any F# project
2. Select menu Project → Properties
3. Scroll to Warnings section and select the dropdown shown above

Expected behavior

a. Only options 0 - 5, as these are the levels supported by F#. b. Descriptions matching the F# spec, not the C# spec (we don't throw C# 11 warnings, do we?)

Actual behavior

Showing 9 options, and showing descriptions not matching F#.

Known workarounds

None.

PS: I've no problem issuing a PR for this, but I've no clue wherefrom this list is populated. This may very well be "external", as in: a bug of VS itself, which is closed source.
