Multiple Push notificatons gateways

Administration -> Settings -> Push -> Gateway
If I set multiple push notification gatways rocketchat server send only to first one
(Multiple lines can be used to specify multiple gateways)

Beсause:
https://github.com/RocketChat/Rocket.Chat/blob/develop/apps/meteor/app/push/server/push.ts#L270
in
private async sendNotificationGateway(

in such "for" logics will work only one time and will exit from a "for" loop after first "return this.sendGatewayPush..." and will not try next gateway from a "this.options.gateways" list.

`for (const gateway of this.options.gateways) {
logger.debug('send to token', app.token);

		if ('apn' in app.token && app.token.apn) {
			countApn.push(app._id);
			return this.sendGatewayPush(gateway, 'apn', app.token.apn, { topic: app.appName, ...gatewayNotification });
		}

		if ('gcm' in app.token && app.token.gcm) {
			countGcm.push(app._id);
			return this.sendGatewayPush(gateway, 'gcm', app.token.gcm, gatewayNotification);
		}
	}`

Start in apps/meteor/app/push/server/push.ts at sendNotificationGateway and inspect how this.options.gateways is iterated. Reproduce the issue with multiple configured gateways and add coverage showing delivery reaches each gateway; done when one push is sent through every configured gateway rather than stopping at the first.
