Remove the labels check from the template

This level of changelog management doesn't make sense for our example repos.

Also it's annoying since the labels don't even exist on the project.

I agree it doesn't make sense for example repos, but it makes sense for something like egui_tiles and ewebsock.

Maybe put it in the Rust-only list in the update-script?

This is a distracting can of worms... gating on rust is hacky. Also the merge-blocking feature is probably worth including, so getting rid of this file altogether is the wrong direction.

The fact that --language needs to be specified every time you update is also annoying, and adding something like --project to it highlights that init should really be creating a persisted configuration file in the repo capturing language, project-type, etc.

I'll just create the labels for now and get back to doing something other than over-thinking the repo templating system.
