Suggestion to add additional GitHub macOS runner

[agracio]

Unfortunately have not been able to spend much time on the project in the last week, but can see that its progressing at an incredible rate.
Have one suggestion for integration tests. Currently macOS runners are set to macos-14 and macos-26 with both using apple M1 arm64 architecture.
Adding macos-15-intel runner will ensure that older macOS x64 is also covered.

I can submit a PR if needed.

I actually wanted to have an x64 mac runner and had specified macos-14-large, but it caused the job to be cancelled immediately due to payment.
It seems all the ones with 'large' in the name are subject to charges. I hadn't noticed the macos-15-intel. Hopefully it's a "free" one.

There are 2 Intel based free macOS runners macos-13 and new macos-15-intel.
macos-15-intel was added very recently and I would suggest to use that one as lately the old macos-13 runner started producing random error in my repos.

Sounds good, can you create a PR?
