Description
When a user is creating a template in Coder from a starter template, they are asked to decide on a bunch of template settings that impact day 2 behavior.
As this may be one of the first workflows in Coder, it creates a significant amount of cognitive load for a new user. I suggest we remove all of these fields (surrounded by red rectangle) on the "create template" screen and create it with the default values:

In comparison, GitHub's "create repo" screen is quite small even though GitHub repos have significantly more settings than Coder settings.

Imagine somebody had to go through all repo settings before creating:

If a user needs to change a setting after creating a repo, they go into the settings for the repo for the full view
Note on "Duplicate"
I think, in many other software platforms, "Duplicate" actions will take you directly to the duplicated resource, not a create form where the user can make modifications before creation.
However, if we want to keep the current duplicate flow, perhaps we could hide the complex fields under "Advanced"
