spotify: use hash instead of sha512 in update script

# just for human consumption. Revision is just an integer that gets increased

# by one every (stable or unstable) release.

revision="${snap_info[0]}"

sha512="${snap_info[1]}"

# We need to escape the slashes

hash="$(nix-hash --to-sri --type sha512 ${snap_info[1]} | sed 's|/|\\/|g')"

upstream_version="${snap_info[2]}"

last_updated="${snap_info[3]}"

echo "Latest $channel release is $upstream_version from $last_updated."

#

# read the current spotify version from the currently *committed* nix expression

#

# search-and-replace revision, hash and version
