Update to the @next

[grzegorz914]

It will be nice if plug-in check which ver. of web UI is installed and if we already are on beta and next beta is available then show update button direct from GUI. Right now we need always run command.

Thanks

v4.29.0 adds the ability to install be beta/test version of any plugin, including the Homebridge core itself, from the UI.

The update notifications are still based on the "latest" tag however.
