CI: Remove simple test from Python Code Quality (OSGeo#3697)

With an error in the code which prevents the simple test of the main executable to run, the Pylint check does not run. While it requires some functionality from the grass executable, it does not require everything to work. This removes the step with the explicit test of the grass executable and relies on other workflows to do that test and provide a reasonable message there. This workflow now hopes to get to Pylint and report an issue with Pylint.

The motivation was OSGeo#3694 where I expected to see a Pylint error, but got a traceback from the main executable in the simple test. (The executable partially worked, enough for config, but not enough for the simple test.)
