Added Rocky 8.10 Repos

[wtripp180901]

The Slurm appliance will be supporting Rocky 8.9 for the foreseeable future so would be nice to have these in here even if they aren't in SKC

I'm not sure the 8.9 mirrors are still available, might have to switch to the vault?

https://at.mirrors.cicku.me/rocky/8.9/README.txt:

This content has been moved to the Rocky Linux Vault

https://dl.rockylinux.org/vault/rocky/8.9/

[wtripp180901]

found a working mirror at https://mirror-nrt.yuki.net.uk/rockylinux/8.9 vault is a bit unreliable when it comes to dependencies so would be good to sync at least one working set

If this is only for Rocky 8.10 now, it might be a good idea to add 8.9 to package-repos-deprecated now it's been synced.

Thanks @assumptionsandg for starting a sync

Yes, since we've now synced 8.9 once, please also add it to package-repos-deprecated
