Fix typos CI

[JoshuaLampert]

The typos CI check in #108 failed after the update. This should fix it again by making an exception for "iz", which is used as a variable name.

Thanks @JoshuaLampert for taking care!

Hm... Downgrade failing, which had not been triggered in #108 . Do you understand what exactly is "Unsatisfiable" here?

[JoshuaLampert]

I have seen that in P4est.jl, too. I'll investigate.

Ok, I have an idea why downgrade failed. It's related to v2.2.1 of the downgrade compat action, where I changed the default julia version Resolver.jl uses. Previously, the default was v1.10 and I changed it to version of the current runtime, which fixed some issues. However, this means Resolver.jl now ran with julia v1.9, which apparently led to some problem with Resolver.jl I do not fully understand. I suggest to just run Downgrade on julia v1.10 since it is the LTS anyway.
I also changed to the forcedeps mode since is the one I prefer because it verifies we have the correct compat bounds set. However, there is another smaller issue with the downgrade compat action because for the JLL packages there are the build numbers +x in the package versions, which are not correctly recognized by the action, which means it fails. I'll see if I can fix that there.

@benegee Please do not merge spell checker updates if the corresponding CI job fails.

[JoshuaLampert]

Should be fixed by julia-actions/julia-downgrade-compat#42.

[JoshuaLampert]

Ok, the Downgrade action is fixed and a new version released. Tests pass again.

Thanks a lot, Joshua!
