The mayor version v2.x.y in contrast with the version v1.x.y the Operative System distribution infix "Linux" is lowercase (v1.x.y is uppercase) for that reason the curl need to be modified, the rest of the script it is the same.

UNAME_S="$(uname -s)"
UNAME_S="${UNAME_S,}"

sudo curl -L "https://github.com/docker/compose/releases/download/v2.10.2/docker-compose-${UNAME_S}-$(uname -m)" -o /usr/bin/docker-compose

You can chain the string manipulation and use an inline command, feel free to improve it!
