Feature Request

• The requested feature would break current behaviour
• I would be interested in opening a PR for this feature

What problem would this feature solve? Please describe.

Add a custom label to the AppLayout Tab of the default route "/" or other routes if "label" is defined. Currently, the label of the default route is always "Home".

routes = [
    solara.Route("/", component=Page, label="Foo", layout=Layout),
    solara.Route("test", component=Test, label="Test123"),
    solara.Route("example", component=Example)
]

Describe the solution you'd like

If the user defines the "label" parameter of a route, the AppLayout Tab should use this naming. In the above examples the AppLayout tabs labels would be "Foo", "Test123" and "example".
