debugbar libraries need to be authorized in vendor_stream_wrapper

Problem/Motivation

vendor_stream_wrapper now uses a list of allowed file patterns (/admin/config/media/vendor-stream-wrapper).
If something like maximebf/debugbar/src/DebugBar/Resources/* is not added, it will refuse to load the libraries.

Steps to reproduce

Don't configure allowed patterns.
/vendor_files/maximebf%3Adebugbar%3Asrc%3ADebugBar%3AResources%3Adebugbar.css returns a 403 error.

Proposed resolution

If we can't automate this, we should at least check for it in a hook_requirements().
