This commit changes the Gutenberg minimum compatible version number from 14.1 (introduced in [54790]) to 16.5. For versions older than 16.5, the plugin will deactivate when upgrading WordPress to 6.4-beta3 or newer.
Changes are done within Core's `_upgrade_core_deactivate_incompatible_plugins()` which is invoked during WordPress' upgrade process.
Follow-up to [54790].
Props hellofromTonya, spacedmonkey.
