checks/label-content-name-mismatch: deprecate occuranceThreshold option in favor of occurrenceThreshold to fix typo
This release adds requirements introduced in WAI-ARIA 1.2, which can result in new issues. The color contrast rule has been improved which should reduce the number of incomplete (aka "needs review") results.
Lastly, this release adds the ability to include or exclude elements inside shadow DOM trees from a test run. See [dom selection] for details.

Deprecate Internet Explorer support
This release may increase or decrease the number of violations reported. This can be because some rules have changed in which ruleset they run (best practice to WCAG, and vice versa). It can also be because the rules themselves got stricter in some places so are able to find new violations, and got more permissive in other places in order to handle more edge cases.
Tags that indicate which success criteria a rule tests violations for have been changed for several rules. In some cases new success criteria tags were added, and in others criteria tags were removed.
Various changes of tags, for greater consistency with ACT Rules.
