Update galaxy-importer ansible-test call to not use docker build

Problem Description:

galaxy-importer calls `ansible-test sanity` in 3 ways

1. Use galaxy-importer's image on quay via openshift job in CRC
2. Use galaxy-importer's image built in real-time when calling importer from the command line
3. Use image provided by ansible-test by calling`ansible-test sanity --docker`

With #2 using `docker build` this is more complex to maintain, not normally expected of a tool like galaxy-importer, and when we update galaxy-importer's image it requires more time for each update. We also use a slightly modified Dockerfile so the images used are not consistent in #1 and #2.

Proposed Solution:

Use galaxy-importer's image on quay when calling importer from the command line. First the quay repository quay.io/cloudservices/automation-hub-ansible-test will need to be made public.
