Add unique and nulls_not_distinct parameters to PostgreSQLIndex so users can create PostgreSQL unique indexes that treat NULL values as equal. This implements the direction from abondar in tortoise#1641: expose the option on tortoise.contrib.postgres.indexes.PostgreSQLIndex instead of changing unique_together behavior. Fixes tortoise#1641
Run make style to satisfy the ruff format and isort (I) checks so the lint gate passes.

Fixes #1641.
Adds
uniqueandnulls_not_distinctparameters toPostgreSQLIndex, so users can createNULLS NOT DISTINCTunique indexes directly instead of relying onunique_together. This matches the approach discussed in the issue: keepunique_togetherunchanged and expose the option on the PostgreSQL-specific index class.Adds regression tests for schema generation and migration SQL output.
