Make trimming paths with slash optional

[szymonmil]

Hi,
When I have some path, eg. /example.html with redirection when there is trailing slash (so /example.html/ will be redirected to /example.html), validation throwing error that i wasn't specified 301 Redirect as possible response. But in my opinion, /example.html/ and /example.html are different paths, and shouldn't be treat the same way.

I'm using ver 0.18
Code providing that utility is here: \League\OpenAPIValidation\PSR7\PathFinder::104

I suggest, to make that behavior optional, for example by passing some config named "trim trailing slashes from path"
What do you think?
