Disable test packaging of MSI on macOS Github runners (#22562)

#22206

This was discussed in the backend weekly.

Currently the test-packaging.yml is extremely unreliable (it has more
failures than successes), because of issues with Docker and colima on
Github macOS runners (we tried docker then colima but both have issues,
timeouts, etc.).

This only removes testing of MSI package generation from macOS. IMO this
is low risk as almost all Fleet devs generate MSI packages from their
macOS workstations.
