Call for review: Element lang correct: remove inapplicable examples

Hey folks,

This pull request removes some inapplicable examples from the "element lang
attribute has correct value" rule. Those inapplicable examples show poor
use of lang attributes, and are failures according to the "lang attribute
valid" rule. If you have any comments, please leave a review by May 5th:

https://github.com/act-rules/act-rules.github.io/pull/1829

Kind regards
