Add "REF" to linkbot

[jdiverp]

last build was 2021 so this may require some finagling with github actions to get a working CD flow.

Ideally also update build to send image to GAR instead of GCR

Have "REF" responses look something like this:
uw-it-linkbot
APP
Title
State
Assigned To <ASSIGNEE
Opened By
Last Update
Related Records <comma separated LIST OF REQS/CASES/OTHER RECORD IN SERVICE NOW WITH LINKS>

[jdiverp]

it is possible we may need to add some additional API calls to get information for REF records. Example REF related records (primary tickets): https://uwconnect.uw.edu/now/nav/ui/classic/params/target/universal_request.do%3Fsys_id%3D5b5a014a97203598e88df7300153af74%26sysparm_view%3D
