Move to unified test runner for GitHub Workflow

[adevade]

This PR moves all tests into one runner, while still running each suite separately with the help of the matrix. It runs all tests even if one matrix fails.

I have looked at and borrowed from Filaments test runner: filamentphp/filament/.github/workflows/tests.yml
