Subject: [PATCH] Add Composer cache step to GitHub workflow

This commit introduces caching for Composer dependencies in the CI workflow using `actions/cache@v4`. It optimizes build times by reusing dependencies across runs, keyed by the `composer.lock` file hash. Removed unused dependency matrix from the PHP job matrix configuration.
