Automate hash calculation; update sources to alma 8.9

[h-vetinari]

Makes it easier to update to newer alma versions (including minor ones). For major bumps, this will even modify the subfolders of the RPMs accordingly.

Builds on #77 & #78, so review those first.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.
I do have some suggestions for making it better though...

For recipe/meta.yaml:

• License exception is not an SPDX exception.

Documentation on acceptable licenses can be found here.

With the automation here, the alma 9 update in #80 only requires the following changes (aside from unavoidable adaptations to infrastructure changes in alma itself):

Let's keep the name here

It just gets very long if we use that prefix consistently... 🤷

FWIW, the changes here are much easier to review commit by commit
