$templates->new doesn't correctly create template

[jlahijani]

If I simply run this as per the /wire/core/Templates/API.md doc :

$template = $templates->new('product');

Then go to the templates section in the admin (/admin/setup/templates), the following error occurs:

TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in wire/modules/Process/ProcessTemplate/ProcessTemplate.module:517
