fix: [#14] resolve tracker database driver configuration issue

- Add TORRUST_TRACKER_CONFIG_OVERRIDE_CORE__DATABASE__DRIVER to compose.yaml
- Update docker-compose.env.tpl to include tracker database environment variables
- Update tracker.toml.tpl comments to reflect both driver and path env overrides
- Update tracker.toml.tpl example to show mysql instead of sqlite3

This fixes the issue where the tracker container was using sqlite3 driver
with mysql connection string, causing database connection errors.

Changes:
- application/compose.yaml: Add mysql driver environment variable
- infrastructure/config/templates/docker-compose.env.tpl: Add tracker DB config vars
- infrastructure/config/templates/tracker.toml.tpl: Update comments and examples
- infrastructure/tests/test-integration.sh: Previous improvements to use local repo
