ci: Run linter workflows on ubuntu-slim or ubuntu-24.04-arm

[weiji14]

Save us some $$. As long as the workflows don't run 3x slower, we should be good.

Oh yay, ubuntu-slim doesn't have cargo. Maybe try on Linux ARM?

It shouldn't be hard/slow to install cargo on the runner. Is there a reason we'd prefer x64 over ARM?

You mean the regular ubuntu-latest x86_64 runnners over the ubuntu-24.04-arm runners? I don't think we're doing any arch-specific things in async-tiff yet, so difference doesn't matter too much when testing. I'm starting to lean more towards ARM runners because they're more cost and energy efficient.
