 Currently the mobile apps rely on the `__unstableGalleryWithImageBlocks`
 flag being
 [https://github.com/WordPress/gutenberg/blob/8fb36dea544e74afc5662a75aeebed6be1fc6077/lib
 /experiments-page.php#L104 set here] in order to enable the new gallery
 block format.

 Because the core release doesn't include the
 `gutenberg_experiments_editor_settings` method, this value could be hard
 coded `get_default_block_editor_settings` method in order to ensure that
 versions of the mobile app >= 18.2 will be able to add and edit gallery
 blocks in the new format.
