[templates] Remove redundant "template" from display name. (#8773)

Fixes: #8626

Removes the word "template" that shows up in the New Item dialog box, as it is unnecessary.

The original issue also mentions not having a custom icon, but as we don't have any of those available, the default icon seems good enough.
