Fix GitHub commit passing, UI build and cache for different purposes (#1239)

* Fix GitHub commit passing, UI build and cache for different purposes

* a logging for transparency and easy debug

* Fix var expanding with quotes and add intermediate verification commands

* split verification commands

* fix joining commands

* Ecplicitly pull latest deps image

* properly set arg default values and try to fix preparation step

* another try to build the image with the correct deps tag

* Revert the dynamic deps tag discovery, as it doesn't work and the actual `latest` image is pulled implicitly anyway

* Final optimizations

* "NoCommit" placeholder, indent fix, var rename
