Expose id on LazyRoute

Which project does this relate to?

Router

Describe the bug

I found this wonderful demo from Balastrong where he uses the RouteId to do some create work with hooks. I want to replicate something similar in my project, but I discovered that the id property is not exposed on LazyRoute instances. It can be accessed with Route.options.id, but as it is stored as a string, it loses all typing. Therefore I opened this issue hoping that the property can be made available on lazy routes.

Steps to Reproduce the Bug or Issue

When looking at the source code of the LazyRoute class defined in the react-router package, the options object is defined as:

{
    id: string
  } & LazyRouteOptions

Because of this, all typing is lost and it cannot meaningfully be used.

Expected behavior

A simple solution is to add the following method to the LazyRoute class:

get id(): {
   return this.options.id as TRoute['id']
}

Additional context

Inspect the LazyRoute class in the react-router package and reproduce the typing issue using the linked StackBlitz example. Expose the route id with its declared type, then verify that lazy route consumers can access the typed id instead of reading options.id as a string.
