Build Pipeline fails with macOS 13

[eopo]

Describe the bug
The build pipeline fails, because it depends on deprecated macOS 13 runners.
This also leads to the home-brew formula not being updated, because that step is never reached.

To Reproduce
Steps to reproduce the behavior:
See https://github.com/robusta-dev/krr/actions/runs/29809991428, especially https://github.com/robusta-dev/krr/actions/runs/29809991428/job/88568652630

Expected behavior
Jobs are updated to supported runners.
