Subject: [PATCH] container/build.sh: FROM_IMAGE=rockylinux-10 default for
 >=tentacle

We build centos9 and rocky10 packages and containers by default now for wip, main, and tentacle branches as of https://github.com/ceph/ceph-build/pull/2557.

Starting with tentacle, we want a `podman pull quay.ceph.io/ceph-ci/ceph:tentacle` or `podman pull quay.ceph.io/ceph-ci/ceph:$SHA1` to get the container with Rocky 10 as the Base OS image, or FROM_IMAGE.

Fixes: https://tracker.ceph.com/issues/75673
