Compatability check CI should also deploy updated plugin registries

[amisevsk]

Description:

During the process for updating the upstream Che dependency version, we're stuck in a state where the PR-check CI job for the "update to version x" PR continues to use the previous versions registries (since it reuses the staging registries). I don't know of any specific issues related to different versions of Che vs. the registries, but this could potentially cause issues in the future.

Instead, the PR-check job should also deploy the relevant plugin and devfile registries, to make the check more accurate.

Background

Previously, the prod-preview registry was updated continuously, so when we created the "update to version 7.x" PR, the PR-check would use the current registry. Now that registries are pinned to the release-preview branch, they are left behind.

Prod-preview seems to be still reliably failing in every test run :D
We are tracking this for the reporting purposes in this rh-che issue: #1635

The logic was added to our PR check. @ScrewTSW please verify it is working correctly and if so, please close this issue. :)
