The repo's config/database.yml already handles both SQLite (default) and
MySQL (DB_ADAPTER=mysql) via ERB. Remove the redundant steps that overwrote
it with a hardcoded version, and pass DB_ADAPTER=mysql for the MySQL job.

- .gitea/workflows/test.yml: two parallel CI jobs (SQLite and MySQL),
each generates its own database.yml inline and runs the test suite
- lib/tasks/test_multi_db.rake: `rails test:all_adapters` runs both
adapters sequentially using DATABASE_URL to switch at runtime
