Issue
Adding an index with a NOT NULL condition incorrectly triggers NOT_NULL rule Adding an index with a `WHERE` clause including `NOT NULL` gets flagged as a `NOT NULL constraint on columns` error. ## Steps to reproduce The follow migration operation: ```python
Files to edit
  • django_migration_linter/sql_analyser/base.py
Approach
Modify the condition that detects NOT NULL to also permit CREATE INDEX statements, matching the suggestion in the issue.

Finish summary
Fixed the NOT_NULL rule false positive for CREATE INDEX with WHERE clause containing IS NOT NULL. The fix added `and not sql.startswith("CREATE INDEX")` to the condition in `has_not_null_column()` function in `django_migration_linter/sql_analyser/base.py` line 46. This excludes CREATE INDEX statements from the NOT_NULL detection, while still correctly detecting actual NOT NULL constraints on columns via ALTER TABLE statements. All 37 tests in test_sql_analyser.py pass, including the specific test `test_create_index_concurrently_where` that was failing before the fix.
