Get all rules for the current language that are built-in or that have been
added using {@link #addRule(Rule)}. Please note that XML rules that are grouped
will appear as multiple rules with the same id. To tell them apart, check if
they are of type {@code AbstractPatternRule}, cast them to that type and call
their {@link AbstractPatternRule#getSubId()} method.
@return a List of {@link Rule} objects
