fix(release): add docker-compose.rootless.yml to released assets (#26261)

* fix(release): add docker-compose files to released assets

Since there is a warning:
"Make sure to use the docker-compose.yml of the current release"

This should apply to other docker-compose files, so it would make sense to release them.

It also makes it slightly easier to get the asset for rootless (e.g., PR 2750).

* release docker-compose.rootless.yml
