Fixes #37606 - Drop old CentOS installation media
The host mirror.centos.org is gone now that CentOS < 9 is EOL. It includes a migration to simplify the name, but doesn't include migrations to remove old entries. That is up to the user because they may have modified them and still use them.
@ekohl did you want me to look for areas that were missed and test(provide a patch), not sure if you just didn't have time or was there another reason this was in a draft?
I tried pushing to your branch to add the migration and I am getting this:
In GitHub you can (don't have to) allow maintainers to push to your PRs. I have that enabled, but since you're not a maintainer and I didn't grant you explicit permissions you get a permission denied.
That's why I suggested to submit a PR against my fork or open a fresh PR. If you'd like to finish the whole effort then I think the latter is easier.
Rebased and squashed. I also expanded the commit message a bit to better describe what's going on.
Rebased and fixed -Stream to -stream.
@Gauravtalreja1 could you take another look?
