Re-order the different ways to deploy a commit

This change is based off empirical data gathered through a live and well-used Deploynaut instance.

Statistics:
* Branch 85.2%
* Redeploy 0.0%
* SHA 9.2%
* Tag 3.4%

With SHA and Branch being the two most used options, Branch is selected by default, with SHA being at the bottom of the list (thus easy to see and click, also that's where it currently is).
