Filter for https mirrors where possible

[Alex-Welsh]

Currently a bunch of the mirrors in these mirrorlists are insecure. This change adds another filter to only use https mirrors

I was looking through the links to make sure that this change won't limit the remaining number of mirrors too much (this seems fine, there's plenty of https ones).
However, I did notice the RL9.1 links are returning invalid:
# repo = rocky-AppStream-9.1 arch = x86_64 error: invalid repo or arch
I realise this isn't a big issue, because we already don't sync these (sync=false). But I'm wondering if it's even worth updating the queries to https in these cases

Yeah, all the RL8/CS8 ones do too. It's just because they're out of date. I think to be honest we need to go through them all and remove all the ones that are broken. But that's a separate job.

I just changed all the RL9 repos
