Hello! 👋

Your PR is changing the image cache. So I am attaching the new image cache
in a new commit.

This commit does not re-run the CICD workflows (since no changes are made in the codebase) therefore
you will see the actions showing in their status Expected — Waiting for status to be reported. Do not worry.
You commit workflow is still running here 😄

You might want to rerun the test to make sure that everything is passing. You can retrigger the CICD sending an empty commit git commit -m "Empty comment to trigger CICD" --allow-empty.

You will see this message everytime your commit changes the image cache but you are not attaching the updated cache. 🤓

@germa89 @Gryfenfer97 Not urgent - but maybe it makes sense to add a unit test that creates a venv with pymapdl but not pyvista and makes sure mapdl can still be imported.
