Docker: disable Jetpack update notices

[simison]

• Disables notices for Jetpack plugin in Docker environment.
• Disables plugin deletions

Deleting or updating the plugin would cause your complete development folder being erased. Not cool.

Previous version of the plugin was already removing the delete link but this disables the actual deletion.

Testing

Probably the easiest way to test is to download older version of Gutenberg: https://downloads.wordpress.org/plugin/gutenberg.2.7.0.zip

...and add it to the list at docker/mu-plugins/avoid-plugin-deletion.php:

$jetpack_docker_avoided_plugins = array(
	'jetpack/jetpack.php',
	'gutenberg/gutenberg.php',
);

Just ensure your gutenberg folder is gutenberg, not gutenberg-2.7.0

Confirm that:

• Update notice dissapears from wp-admin and the Activity log:
  
  
• Bring back plugin deletion link by commenting out unset( $actions['delete'] ); in the code and press delete Gutenberg from /wp-admin/plugins.php. You should see this error:
  

CLI

Sadly deleting the plugin via cli still works: yarn docker:wp plugin delete gutenberg

Notes for future reference:

if ( class_exists( 'WP_CLI' ) && method_exists( 'WP_CLI', 'add_hook' ) ) {
	WP_CLI::add_hook( 'before_invoke:plugin delete', function () {
			// How to recognize which plugin is about to be deleted?
			WP_CLI::error( 'Nope!' );
	} );
}
