CI: Add new core pathogens to pathogen-repo-ci

[joverlee521]

We test pathogens as part of Augur CI to ensure changes don't break automated pathogen builds.
We've recently added multiple pathogen repos that are not being tested yet:

• hmpv (depends on Conform to pathogen-repo-ci hmpv#3)
• oropouche
• rabies
• wnv
• yellow-fever

The hmpv repo will need to be updated to conform to the pathogen-repo-ci, but everything else can be directly added.

Ah, with upcoming nextstrain/docs.nextstrain.org#241, we might also want to visit #1350.

Should similar issues be created for conda-base and docker-base?
