fix: Add alias_tokens parameter to _parse_join() for sqlglot 30.9.0 compatibility

- Add missing alias_tokens parameter to _parse_join() method signature
- Pass alias_tokens to internal __parse_join() calls
- Maintain backward compatibility with optional parameter
- Fixes TypeError when using sqlglot 30.9.0 or later

Resolves compatibility issue where SQLMesh's _parse_join() override
was incompatible with sqlglot 30.9.0's updated method signature.
