🪲 No further validation in the presence of anyOf. Always true.

The reason for this change: #850

Test case (add in openapi3filter/validate_request_test.go):

We are waiting for the error minimum string length is 17, but there is no error.

func TestValidateRequestInvalidStringLength(t *testing.T) {
	const spec = `

	body := strings.NewReader(`{"vehicle":{"identifiers":{"vin":"BAD"}}}`)
	req, err := http.NewRequest(http.MethodPost, "/tech", body)

	req.Header.Add("Content-Type", "application/json")

	router := setupTestRouter(t, spec)
	route, pathParams, err := router.FindRoute(req)
	require.NoError(t, err)

	err = ValidateRequest(context.Background(), &RequestValidationInput{

		PathParams:  pathParams,
		Route:       route,
		QueryParams: req.URL.Query(),

	require.ErrorContains(t, err, "minimum string length is 17")
}

Similar properties are similarly not validated. minLength is taken as an example.
