Storing latest tag as well so that artifacts are not needed.

For now not removing artifacts until the internal script is updated to handle this change.

----

Task A-8: Prefixing branch name to the docker tag along with the date.
In the internal script we will not need to maintain the different branch lists as the images will be completely tagged in the external workflows themselves.
We can simply use the tags without modifications then.

For now, not prefixing the tag to the artifact since we will be removing the artifact anyways.
And current internal script works with artifacts.
Once I update the internal script, will come back and remove artifacts.

Internal script updated as well.
Internal PR must be merged as well once these external PR changes merged.
