Fix pushing to 1-x-dev docker tag (#18578)

* Fix pushing to 1-x-dev docker tag

It appears that #18551 and #18573 have a mistake in that raymond does not have
an {{else}} on {{#equal}}. This PR notes that Sprig has a hasPrefix function
and so we use this with another if.

* Fix pushing to 1-x-dev docker tag (part 2)

Although we now have the manifest working, we need to create the images.

Here we adjust the .drone.yml to force building of the images

dev and the release/v* ones become *-dev-*
