The PR build is sufficient for the PR pipeline. I did not test publishing specific to 5.5, but I did test it in https://github.com/gravitational/planet/pull/813. The jenkins job uses the same logic for all branches, so I'm not concerned that something 5.5 specific will break.
This is the 5.5 backport of https://github.com/gravitational/planet/pull/812 and https://github.com/gravitational/planet/pull/813. The changes are verbatim.
