Configure actions/upload-artifact action to upload hidden files

A breaking change was made in the 3.2.1 release of the "actions/upload-artifact" action, without doing a major version
bump as would be done in a responsibly maintained project. The action now defaults to not uploading "hidden" files.

The dependency license metadata cache is stored in a folder named `.licensed`. The "Check npm Dependencies" workflow
uploads the generated cache as a workflow artifact when the current cache is found to be outdated in order to facilitate
the update of the cache.

The `.` at the start of the `.licensed` folder name causes it to now not be uploaded to the workflow artifact. In order
to catch such problems, the workflow configures the "actions/upload-artifact" action to fail if no files were uploaded.
So the workflow now fails:

Error: No files were found with the provided path: .licenses/. No artifacts will be uploaded.

The problem is fixed by disabling the "actions/upload-artifact" action's new behavior via the `include-hidden-files`
input.
