Change the default FRR docker image repository

This patch changes the default reporitory (hub.docker.com) to quay.io,
in order to avoid the limitations implemented in the website, reducing
the download request. The base image is the same: Ubuntu 22.04

NOTE: it could be possible that quay.io implements the same limitations.
