[Done] [Beta] Start form name editing after creating a form

[stefano.menci]

After clicking on the + Add Form button, a form called Form1 is added to the app.
The next step is always to right-click on it and rename it.

The editor should automatically be in form renaming mode.

Found this in the March 2023 changelog. I tested it out, and…sure enough!
