Group-level project templates: Mini renaming

Group-level project templates will finally be available with 11.6 in December 😍.

In our Manage Monthly meeting, @dennis provided an awesome preview of this feature. I found a mini detail I'd like to change. When you are on the "Create from template" tab, we have three sub-tabs, "Built-In", "Instance", "Group".

Can we rename "Built-In" to "Built-in"? Thanks @dennis 🙈.
