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)
Black dependency created a dependabot warning and couldn't be bumped since it collided with pathspec dependencies. Since ruff can also format, black is not needed. But we now have these small format changes, mostly in test files
Add _extend_nix_symbol_range_to_include_semicolon method to prevent
double semicolons
Add test_nix_symbol_replacement_no_double_semicolon to validate the fix
