Fixes #26362

Thanks @Mugurell, I am glad to take actions to fix the issues.

This pull request changes the usages of android:lineHeight to app:lineHeight. Now the line height should be consistent among API levels.

Looks great! Thank for the investigation and fix!
To remove all traces about android:lineHeight can you also remove the suppressions from lint-baseline.txt?

Thank you for also organizing the work in multiple commits but probably just one Replace android:lineHeight with app:lineHeight to support lower api levels commit is enough. You could create a new commit for removing the now unneeded warning suppressions from suppressions from lint-baseline.txt if you'd like.
