[VS Code] Update Code Suggestions status text for user-disabled languages

The following discussion from !1689 (merged) should be addressed:

• @markrian started a discussion: (+1 comment)

  note: This is the message currently shown if the user has disabled Code Suggestions for a particular language.

  Should we change that in this MR? Or is it reasonable to address that in a follow up?

Proposed implementation

From !1689 (comment 1980637433):

Given that the user can now enable any language, what about Code suggestions are disabled for this language. Ideally, we should better explain the situation about what languages are supported/unsupported and what quality of results to expect. But I do not think this should be done in the scope of this MR.
