Some Linux aarch64 builds are failing on` main`

As noticed in recent CI runs: https://github.com/PyWavelets/pywt/actions/runs/13011362250/job/36289627702

The logs are quite verbose with pip backtracking a lot and displaying a lot of links (don't know why; that usually happens when CIBW_BUILD_VERBOSITY is set to 3, but we've set it to 2), but the error is that the compiler cc can't compile programs – it's probably broken, or these failures were just flakes.

I think it makes sense to try out the Arm runners for these builds, given that the initial issues with their rollout have more or less been resolved and reports are quietening down with each passing day.
