Integration with validation library?

[zajimumaaa]

Is your feature request related to a problem? Please describe.
It's a bit tedious to validate request body and query param and then manually return appropiate error message, it would be nice if there's some kind of integration with validation library that remove boilerplate to validate and return appropiate error message similiar to python web framework like fastapi that integrate with pydantic.

Describe the solution you'd like
Integration with validation library like validator or garde. Currently garde has an integration with axum here that may be used as reference to integrate garde to salvo

Describe alternatives you've considered
