I see more than one thing here:

Bugs

• Not redirecting to the template UI after publish
• The new version name in the modal is not correct. It is using the previous one

Feature

• Disable the build button if there are no changes to apply

This was done as a part of #9153, which responded to an issue (#7153) that I originally proposed to Bruno. When someone is rapidly iterating on a template, it can be frusterating if you get constantly redirected if you want to stay in the editor. However, I can see how it is equally frusterating if there isn't a clear confirmation your new version was published or maybe there are cases where they want to back to the template UI. Without a clear "you have saved this version" dialog, I can see how this would come across as a regression.

One suggestion is to add a dialog:

The version rapid-carrot has been published. The version [is/is not] promoted to all users.
[CTA: Create workspace from version (to test your changes)?]

This wording isn't perfect, but may help with the confusion. Alternatively, we could revert the PR and always redirect. Will defer to @BrunoQuaresma and @aslilac here :)

I saw @aslilac also suggested a "publish and keep editing" option. I'd be open to something like this in the dropdown as a secondary option

I was able to return the template dashboard UI

You can still do this navigation by clicking on the name of the template while in the editor, but we might want to make that more noticeable somehow.
