--------------------------------------+-----------------------------
 In classic themes that have the `block-templates` theme support I've found
 that block templates with certain names become unmanageable after
 creation. This seems to be because their slugs are special or reserved in
 some way.
 The two names I've found so far are "home" and "archive".

 If you create a block template with these names, they are still used on
 the frontend as normal. However, they do not appear in the list of
 templates you can edit and trying to access them from the template
 editor's command palette leads to an error reporting: "The theme you are
 currently using is not compatible with the Site Editor."

 This means that I can create a template that will potentially get used as
 my site's archive template, but I cannot edit or remove it.

 I would expect any block template I can create in a classic theme through
 the template editor to be manageable from there as well.
 Otherwise, if I shouldn't be able to manage these templates, then I
 shouldn't be able to create them either.

 **My Test Environment**
 - WordPress: 6.6.2
 - PHP: 8.1.9
 - MySQL: 8.0.16
 - Theme: Twenty Twenty One with `block-templates` theme support added.
 - Plugins: none

 **Steps to Reproduce**
 - Create a new page.
 - Click the template button.
 - Choose to create a new template.
 - Name the template "archive"
 - Save the template. (you may see an error that saving failed)
 - Check the wp_posts table for a new wp_template post, see that the
 "archive" template is in the table.
 - Load an archive page on your site, see that the new "archive" block
 template is being applied.
 - Go back to editing the page and refresh the page
 - Click the template button.
 - The "archive" template just created does not appear here and cannot be
 edited.
