Allow parse expressions with Request::validate facade usage

[geangontijo]

I have a project that use Facades to validate, then i think that this is useful.

Docs update:

• Allow parse expressions with Request::validate facade usage scribe-docs#31

I run locally tests:

Thanks! Can you add a new test? You can see the example of Validator::make here?

I have a observation about the tests that i maked:

I not replicate the GetFromInlineValidatorTest::respects_query_params_comment for Facade version because i think be a context from Knuckles\Scribe\Extracting\Strategies\BodyParameters\GetFromInlineValidator.

I your think this is a wrong interpretation of my part, i stay free to make changes
