When olivero is the base theme

@sime thank you for the code and the issue. I have updated the code to move the check into a separate function just in case, in the future, we come across another way of checking if a theme is related to Olivero. Let me know if this change still work as expected for you and this issue should be ready for commit.

That appears like a good appraoch. I do not work on the project anymore, and we stopped using this module, however it seems right to me.
