[CI] Exclude docs directories from triggering rebuilds
Currently when someone touches a docs directory in a subproject, it is
treated as if the source code of that project got touched, so the
project is built, it is tested, and the same for all of its enumerated
dependents. This is wasteful, particularly for patches just touching
docs in places like LLVM where we might spend an hour of node time to do
nothing useful given changes in the docs shouldn't cause test failures
and there is already another workflow that tests the documentation build
completes successfully.
