[next-devel] manifest: add fedora-candidate-compose to list of repos

[dustymabe]

Late in the Fedora major release process adding this repo will
allow us to pull in candidate RPMs that are proposed to fix
release blocking or freeze exception issues. We will be able to
test out these proposed fixes sooner and also be more prepared
for releasing our final next release once the release is
deemed "Go".

See #2705

Before we merge this, I think we clear up first whether the repo should always be in the manifest or only during a certain period. Maybe let's have a quick high-bandwidth chat about it.

Updated the commit message here.

FTR: @dustymabe and I discussed this OOB and we agreed that outside of this time period (lead up to GA), we will go back to using the official Fedora repos only.

Since (as expected) this hasn't changed any packages in the compose:

I'll go ahead and merge this. skipping the rest of CI

Slight clarification. I think it should be: "outside of this time period (when next is on pre-release Fedora 'next'), we will go back to using the official Fedora repos only."
