rusackasandClaude Opus 4.8 03ebf2add4 fix(testcontainers): address remaining reviewer feedback (db2 arm64, cockroachdb DBAPI docs, stale workflow refs)
- requirements/development.in + testcontainers.yml: scope the `db2` extra
  (`ibm-db-sa`/`ibm-db`) out of the baseline dev install. `ibm-db` ships no
  Linux arm64 wheel, so bundling it there broke the multi-platform dev
  Docker image build on push. The testcontainers CI job now installs it
  directly, only for its own db2 matrix leg.
- cockroachdb.py: list `psycopg2-binary` alongside `sqlalchemy-cockroachdb`
  in the `pypi_packages` metadata, since a plain `cockroachdb://` URL can't
  connect without a DBAPI and sqlalchemy-cockroachdb doesn't install one.
- test_cockroachdb.py/test_crate.py/test_trino.py: fix stale docstring
  references to the old `nightly-testcontainers.yml` filename.
