A better solution for skipping CI steps for docs-only changes. (pants…

…build#16053) The previous solution involved some complexity in extracting the filenames from JSON, and was not robust to spaces in path names (we do have such paths under docs/). Instead we use a different GHA marketplace action. This one is more featureful, and allows us to specify a subset of files to look at, so we don't need to do the filtering ourselves. We can just check if the filtered set (everything except docs/**) has any changes in it.
