fix GHA invocation of docker tag push script

[tarilabs]

The goal of this PR is to fix 2 issues in the current GHA invocation:

• VERSION needed to be pass down to push the tagged layer (the layers and rolling tags are already pushed from the steps above, what needs to happen is GHA need to instruct the script to just-push the newly created tag)

Description

With this change:

• ensure latest and main tag are synced to the most recent image produced (except of release versions)
• we can always introduce a latest-release tag following similar GHA snippet later

DCO for GitHub suggestion being applied
Hi, Just thought of headsup to the KF community leaders, it seems to me some GitHub configuration is needed for those commits coming as GitHub Review suggestions, as allegedly they are the ones failing some automated DCO check.
Example: #30 (comment)
Thank you, hope this helps
