Update from macos-12 to macos-13

[VocalFan]

This is due to macos-12 soon being deprecated: actions/runner-images#10721

As such, I bumped our runners that are using macos-12 to macos-13. Not macos-14, as that is an ARM64 based runner as shown here:

macOS 13	macos-13 or macos-13-large	macOS-13
macOS 13 Arm64	macos-13-xlarge			macOS-13-arm64

As long as macos-13 is used and not macos-13-xlarge, we'll stay on the intel platform.

Not sure if this is really a ME thing but...

Strange. AFAIK hv-sys embeded a generated binding instead of generate it from the computer it is running. Switching macOS version should not cause this error.

[VocalFan]

Yeah, and I'd rather our builds not get halted by "brownout" periods to make developers move to a newer version than macos-12

@SuchAFuriousDeath do you want to maintain this? If not I think we should remove macOS x86 because no one want to maintenance it. It is going to die anyway since Apple already moved to ARM.

[ultimaweapon]

Let's remove macOS x86.

[SuchAFuriousDeath]

I agree.
