The recommended way to add repo for apt becomes:

deb [signed-by=/usr/share/keyrings/google-cloud-ops-agent-keyring.gpg] https://packages.cloud.google.com/apt google-cloud-ops-agent-focal-all main

While osconfig-agent add-pkg or add-repo still uses:

deb https://packages.cloud.google.com/apt google-cloud-ops-agent-focal-all main

Is there any plan to update osconfig-agent on it's add repository method?
