Use default arch in CI

[JoshuaLampert]

There are warnings (e.g., https://github.com/JoshuaLampert/DispersiveShallowWater.jl/actions/runs/12108289323) in the CI runs because we request x64 on a macOS runner with arm64. I propose to simply use the default architecture, i.e. to remove the arch argument. For the flag-name of the coveralls action I followed the example under https://github.com/coverallsapp/github-action?tab=readme-ov-file#complete-parallel-job-example.

So it seems CI uses another Mac machine now, which allocates a bit more for one test and needs some adjusted tolerances.
