Optimize test workflow by removing unnecessary package manager installations

Only Package Handlers tests need all package managers installed since they test the fix functionality.
Other test suites (Unit, Scan Repository, Scan Pull Request) don't need npm, Python, pipenv, poetry, Mono, dotnet, NuGet, Pnpm, Java, or Conan installations.

This will significantly speed up test execution for non-Package Handler test suites.
