* Add devel repo to list of repositories to migrate.

* Use baseurl from our CentOS vault mirror.

CentOS killed off all the CentOS 8 repos and moved them to vault.  As a result
migrate2rocky was no longer working to migrate CentOS 8 installs.  To fix this
we've mirrored the CentOS 8 vault and point migrate2rocky to that instead.
