Add getValidatedRouterParams(event, validate)

[atinux]

Describe the feature

Similar to getValidatedBody(event, validate) but for router params.

Additional information

• Would you be willing to help implement this feature?

We have readValidatedBody and getValidatedQuery and we could add a getValidatedRouterParams to get a typed result.

On a s side note, I feel like we have some naming inconsistencies ;

• according to express the precise terminology is route parameters. I think both routerParams and routeParams are confusing because of queryParameters (which maps to getQuery)... Maybe we could consider a different name, like getUrlSegment ?
• we currently use both readX and getX ? Could we use getX for everything for the sake of consistencies?

Isn't a little nuance like explained here, https://stackoverflow.com/questions/23664175/whats-the-difference-between-read-readsome-get-and-getline?

This would be a great feature to add.
Right now I'm still using h3-zod primarily because useValidatedParams, which is pretty much the proposed getValidatedRouterParams(event, validate)
