fix(ci): remove macOS tests from CI

[oxarbitrage]

Motivation

We have crashes in every PR after rust upgraded to 1.70 in macOS tests. We don't know what tests are causing it so we are disabling all tests for this platform as they are not supported by Zebra in tier 1.

Fixes the CI error in #6812, but not the underlying bug.

Solution

Remove all macOS tests from CI.

Review

Anyone can review.

Reviewer Checklist

• Will the PR name make sense to users?
  • Does it need extra CHANGELOG info? (new features, breaking changes, large changes)
• Are the PR labels correct?
• Does the code do what the ticket and PR says?
  • Does it change concurrent code, unsafe code, or consensus rules?
• How do you know it works? Does it have tests?

Follow Up Work

I am a bit surprised, but my PR actually seems to fix the underlying bug:
#6820

The test failures I saw were easy to fix.

So let's leave this one in draft until we see if that one passes CI?

That is even better, so yea, lets do that.

Looks like my PR didn't work, let's try this one.

Thanks for this.

I left the issue open because the bug isn't actually fixed, but I changed its priority to low.
