Restore the config template in the autogenerated config file

[steven-tk]

What do you want to change?

I have found what appears to be a bug and already have a suspected fix.

While setting up a new Mac and installing Ghostty I noticed the config being empty - I remembered the config template being useful and would like to restore previous functionality.

Why do you want to make this change?

An empty file with a missing template is not a critical issue but made me stumble and I am sure other (especially new) users would appreciate restoring what is currently broken.
