macOS builds no longer run when with a quarantine attribute due to incorrect codesigning

macOS builds no longer run when with a quarantine attribute due to incorrect codesigning

Repro Steps:
1. Download a mac editor (2021.1.x for instance)
2. Once downloaded, build a mac player
3. Move mac player to a different mac and try to run

Actual Result
A new error shows up (it started to happen around mi-December 2020 for me an a colleague) : "<Unity app> is damaged and can't be opened. You should move it to the Trash"

Expected Result
Before it started happening, another dialog was showing up and I could still open the app: "macOS cannot verify the developer of "<Unity app>. Are you sure you want to open it?"

Workarounds (you only need to apply one):
- After exporting the game on a path, resign the whole app bundle: "codesign --deep -s - -f path/to/game.app"
- Remove the quarantine attribute from the command line: "xattr -r -d com.apple.quarantine path/to/game.app"
- User an GUI app to strip the flag: xattred

    Hi everyone, as far as we are aware, this issue is fixed in all known cases. If you're still running into "<Unity app> is damaged and can't be opened. You should move it to the Trash" error in Unity versions where it's listed as fixed, please either report a bug, or post to our macOS forum (https://forum.unity.com/forums/macos.95/) and we'll make sure to investigate/help you!

    I did the following workaround to successfully open the app files on my M1 computer.

    Remove the quarantine attribute from the command line: "xattr -r -d com.apple.quarantine path/to/game.app"
