Add weekly component contribution report

What does this MR do and why?

Describe in detail what your merge request does and why.

This will create a new weekly report that will triage any new or stale component contribution MRs in gitlab.com/components to support development of components that will be available in the CI Catalog. The group to be pinged on this list requires thought on who should be aware of these MRs.
