Code action to add import for extension method in Scala 3

[ckipp01]

Is your feature request related to a problem? Please describe.

When working in Scala 3 you will at times get diagnostics that mention that an import may fix the problem. For example I just tried using "someString".toTermName and Scala 3 returned this as a diagnostic

Diagnostics:
1. value toTermName is not a member of String, but could be made available as an extension method.
   
   The following import might fix the problem:
   
     import dotty.tools.dotc.core.Decorators.toTermName

Describe the solution you'd like

In this situation I think it'd be perfect to also have a code action that can be triggered on toTermName which will offer to add the import in the same way we treat a Not Found: diagnostic. In this case, the code action would import dotty.tools.dotc.core.Decorators.toTermName

Describe alternatives you've considered

Manually adding it.

I think this is exists already in terms of #105 and #141. How do I know? Because I've duplicated it too in the past (see #192).

Also worth mentioning my half-assed attempt at implementing it scalameta/metals#2536

👀 I maybe didn't search before creating this like I should have 😆
