fix: Add squid branch in builds

[afreen23]

Squid branch is missing in ceph-dev builds.
This PR adds that.

Also disables google chat notification as we no longer use google chat.

Finally, after crazy attempts, I have come to know that "secrets" are not passed into PRs and thats why docker login failing here.
See https://stackoverflow.com/questions/78081249/github-actions-fails-to-access-secrets

Workflows triggered via pull_request_target have write permission to the target repository. They also have access to target repository secrets. The same is true for workflows triggered on pull_request from a branch in the same repository, but not from external forks. The reasoning behind the latter is that it is safe to share the repository secrets if the user creating the PR has write permission to the target repository already.

So let me raise a separate branch in the ceph-dev repo and try it.
