Description

Using saveEntityRecord() to save a template stopped working in a recent update of Gutenberg.

I believe the issue was introduced in #67125 (cc @ellatrix), specifically where the wp_template rest_base is modified:

Step-by-step reproduction instructions

1. Switch your theme to TT4.
2. Add this code snippet somewhere in your site/plugin:

const { saveEntityRecord } = dispatch( coreStore );
saveEntityRecord(
	'postType',
	'wp_template',
	{
		id: 'twentytwentyfour//home',
		content: 'test',
	},
	{
		throwOnError: true,
	}
);

3. With Gutenberg disabled, notice a query to /wp-json/wp/v2/templates/twentytwentyfour//home is done, and it works. With Gutenberg enabled, the query is done to /wp-json/wp/v2/wp_template/twentytwentyfour//home and it returns this error: No route was found matching the URL and request method..
