[java] Fix reference to removed withTagName method in RelativeLocator class comment
* position on the DOM. Elements are returned ordered by their proximity to
* the last anchor element used for finding them. As an example:
* <pre>
- * List<WebElement> elements = driver.findElements(withTagName("p").above(lowest));
+ * List<WebElement> elements = driver.findElements(with(tagName("p")).above(lowest));
* </pre>
* Would return all {@code p} elements above the {@link WebElement}
* {@code lowest} sorted by the proximity to {@code lowest}.
