Add integrity checksums
Hi,
I noticed that https://git.getcryst.al/crystal/misc/iso/-/releases/permalink/latest does not have an integrity checksum or similar checks (like the ones in Arch Linux's Checksums section). Would it be possible to add one? This is the SHA256 of the ISO I get from the Google Drive download link:
$ sha256sum crystal-live-2023-10-27-x86_64.iso
