Define the default template for template creation in theme.json

[carolinan]

What problem does this address?

When users create a new custom page template from the block editor's Template section, WordPress uses a basic template with a few selected blocks.

What is your proposed solution?

I know there is a lot of ongoing work to improve the template creation flow ❤️. It would be an additional improvement for theme developers if they could define a template html file to be used as the default.

This could be part of the customTemplates section in theme.json:

	"customTemplates": [
		{
			"name": "page-without-title",
			"title": "Page without title",
			"default": true
		}
	],

Probably a duplicate of #36086, but in this case, I think we can close the old issue.

P.S. I like the idea of using the default flag in the definition.

That would be so incredible helpful to have. It's not a great experience for users to have to switch the template from default every time. For our block themes, we would much rather have our Header & Footer only Template be the default one.

Yes, it is the same issue, I could not find #36086 when searching :)
