RR0201 Convert interpolated string to 'string.Format' not showing up

[deerchao]

Refactory RR0201 option not showing up, while other refactoring and code fixes are working as expected in VS2022 and VS 2026.

It seems I was wrong. In fact, NONE of the refactorings are showing up, but the analyzers and code fixes are working.

Update: the visual studio extension worked, not the nuget package.
