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
