Docs: Correct @since tags introduced in WordPress 6.0.1.

The associated changes were backported to the 6.0 branch, so the version should be 6.0.1 instead of 6.1.0.

This affects:
* `@since` tag for the `block-templates` feature in `create_initial_theme_features()`.
* `@since` tag for the `show_on_front`, `page_on_front`, and `page_for_posts` options on the REST API settings endpoint.

Follow-up to [53590], [53661].

Props tommusrhodus, johnbillion.
Fixes #56225.
