[Feature Request] Make Dash pages callback `hidden=True`

[antonymilne]

In Dash 3.3.0rc0, callbacks can be hidden from the callback graph in debug mode with hidden=True. I would have thought that the Dash pages callback would be a great one to hide. I think it doesn't do anything useful in the graph and just clutters it up.

Good idea, the hidden feature is for cases just like this.
