Add controller type to create project wizard

[PeterJohnson]

From wpilibsuite/2024Beta#5:

My impression is the list of project templates could benefit from reordering or reworking.
It's quite long and if you don't know which option you want going in it could be very confusing.
Maybe another selector in the wizard where you select the controller platform before selecting the project type? (roboRIO/Romi/XRP)

Do we need to add a value in the JSON to provide this? Potentially we could avoid that because the gradlerio value could be used to disambiguate since the three use different values, but it might be cleaner to just have a separate value.
