chore: remove Nix and replace with shivammathur/setup-php in CI (#211)

* chore: remove Nix and replace with shivammathur/setup-php in CI

Nix added complexity and slow build times to the CI pipeline. All
workflows now use shivammathur/setup-php for PHP provisioning, which
is the standard approach for PHP projects on GitHub Actions.

* chore(ci): update workflows to use PHP 8.4 and adjust compatibility

* chore(ci): update PHP extensions and enable xdebug for coverage
