Fix symbol name resolution in selected LS (#1247)

Adds tests for name resolution for each language and fixes the name resolution where tests have failed.

Also:

Extends python tests to cover ty
Extends skipping conditions for several LS (but only when not in CI)
Better test output in CI
Removed a wrong python test (started failing for ty and should have failed for pyright too)
