Manage foreign resources registered with ResourceLoader.

This helps developers with downloading, verifying, and updating local copies of
upstream libraries registered as ResourceLoader modules. See
https://www.mediawiki.org/wiki/Foreign_resources

Use the "update" action to download urls specified in foreign-resources.yaml,
and unpack them to the resources directory. This will also verify them against
the integrity hashes.

Use the "verify" action to verify the files currently in the resources directory
match what "update" would replace them with. This is effectively a dry-run and
will not change any module resources on disk.

Use the "make-sri" action to compute an integrity hash for upstreams that do not
publish one themselves. Add or update the urls foreign-resources.yaml as needed,
but omit (or leave empty) the "integrity" key. Then, run the "make-sri" action
for the module and copy the integrity into the file. Then, you can use "verify"
or "update" normally.
