Context:

I have a custom type, implementing encoding.TextUnmarshaler, that returns a domain error upon failed unmarshaling. This error is somehow not propagated to my ErrorHandler

Expected behavior:

Upon my custom path parameter type being bound in BindStyledParameterWithOptions, the parameter is recognized as an encoding.TextUnmarshaler, and when the domain error it returns can be errors.As'd inside the ErrorHandler setup as

openapi.RegisterHandlersWithOptions(srv.router, srv, openapi.GinServerOptions{
	ErrorHandler: inboundErrHandler,
})

Actual behavior:

In BindStyledParameterWithOptions, errors is wrapped as fmt.Errorf("error unmarshaling '%s' text as %T: %s", value, dest, err), which loses all information about the error, making error handling in the Handler more difficult

Proposed fix:

BindStyledParameterWithOptions should return errors wrapped as %w instead of %s/%v (there seems to be inconsistencies as to which is used).
