Update CI configuration to upgrade pip and install PGroonga extension

- Added a step to upgrade pip to the latest version to avoid warnings about outdated pip.
- Added steps to install the PGroonga extension and restart PostgreSQL to ensure the schema exists.

This resolves issues with the outdated pip version and the missing PGroonga schema during the CI process.
