Add command-line options for FCGI connection and align CI

[trombini77]

Context

This PR enhances the PHP-FPM healthcheck script by adding command-line options for FCGI connection parameters (--fcgi-connect and --fcgi-status-path), allowing more flexible configuration. It also updates the test suite, expands Makefile support for broader PHP versions (8.2-8.4) and distributions, and aligns the GitHub Actions CI workflow to match the Makefile's test matrix for consistency.

OBS: php container images based on Debian Buster and olders were removed because the OS packages are not more available (apt commad fail) like this:
