The original REST API revisions controller relied on `wp_get_post_revisions()`, getting all revisions of a post without any possibility to restrict the result. This changeset replaces that function call with a proper `WP_Query` setup, replicating how `wp_get_post_revisions()` works while offering parameters to alter the default behavior.
