[PRQ#69217] Deletion Request for proton

loathingkernel [1] filed a deletion request for proton [2]: I would like to focus my maintenance effort on a single proton version and since the way of building proton in this package is unsupported by upstream, I would prefer for it to be deleted. [proton- cachyos](https://aur.archlinux.org/packages/proton-cachyos) should server as a replacement that focuses on being built without Valve's Steam Linux Runtime.
