bug: lingering linter diagnostics

[gnikit]

Is there an existing issue for this?

• I have searched the existing issues

Description

I am not sure how well defined this behaviour is and I need to investigate further but I noticed that the latest versions of the linter seem to not be updating the diagnostics when we go from errors -> no errors. That seems to indicate that there is a lingering state that does not get disposed.

Clearing the diagnostics via the command palette seems to resolve the issue.

This issue was also noticed in the fpm project
