SwiftFormat removed from macOS 12

[bdrelling]

Description

SwiftFormat 0.49.7 is on the macos-11 runner: https://github.com/actions/virtual-environments/blob/main/images/macos/macos-11-Readme.md#tools

But it's missing from the macos-12 runner: https://github.com/actions/virtual-environments/blob/main/images/macos/macos-12-Readme.md#tools

1. Why was it removed? I can't find any news or information on this.
2. Can it be added back? SwiftFormat is an extremely widespread tool. If macos-12 includes SwiftLint, it should probably also include SwiftFormat.

Hey @bdrelling, We will pre-install SwiftFormat on macOS-12.

@al-cheb Incredibly quick response, really appreciate it!

I'm not sure how to keep up with changes to the runners, do you know when/how this would be added to the image?

In the meantime, it is simple enough to add a brew install swiftformat step for now, so this isn't urgent, just inconvenient.

Thanks again!

The new image has been deployed with swiftformat on board.
