Browse all template link does not work in site editor

[olein]

When I click Browse all template button on site editor, this button doesn't work at all.

URL was changed from http://localhost:8888/wp-admin/site-editor.php?canvas=edit&path=%2F to http://localhost:8888/wp-admin/site-editor.php?canvas=edit&path=%2F&postType=wp_template.

Additional information: I have confirmed the operation in the following environment.

• WordPress 6.2 Beta 3
• Twenty Twenty Three activated
• No plugin

Incidentally, if you display another template that is not HOME (for example, 404) and click the Browse all template button, the Site Editor display will return to HOME, but the template list will not be displayed.

Therefore, I feel that there may be other optimal behavior when this button is clicked.

I think this problem is also reported in the gutenberg repository: ​https://github.com/WordPress/gutenberg/issues/48289

The PR that fixes this problem is below:
​https://github.com/WordPress/gutenberg/pull/48301

This PR will be backported to WordPress 6.2 Beta4.

@wildworks Thank you! It was not enough research by me.
