qa/suites/upgrade/telemetry-upgrade/quincy-x: update image reference

`quay.io/ceph/daemon-base:latest-quincy` points to the latest quincy tag (v17.2.7),
not the tip of quincy, which is actually what we want to test.

Pulling the daemon-base:latest-quincy image shows it is running v17.2.7:
```
lflores:ceph$ podman run --rm -it daemon-base:latest-quincy
[root@e4eb265e7fa0 /]# ceph -v
ceph version 17.2.7 (b12291d110049b2f35e32e0de30d70e9a4c060d2) quincy (stable)
```

It is important that we test the tip of quincy in case there is a fix there that
we want to pick up.

I referenced this commit to make the change: https://github.com/ceph/ceph/commit/d0381ed7e68a6de7c9ff1e4220698ed8eab28ac6
