Bring Parsing in spec with the release of WCAG 2.2

Is your feature request related to a problem? Please describe.

WCAG 2.2 removes the success criterion 4.1.1 Parsing (Level A). In addition, with the release of WCAG 2.2, Parsing is deprecated in WCAG 2.0 and 2.1, and the criterion is updated in those versions to always be considered satisfied by any content using HTML or XML.

The Accessibility Insights extension reflects this update with a small "Deprecated for WCAG 2.2" notice, which is not completely accurate, and the test does not reflect current WCAG guidance.

Describe the desired outcome

Remove the Parsing test from the guided Assessment.

Describe alternatives you've considered

Update the Parsing test automatically pass if the detected content is XML or HTML, and describe how to test for non-XML/non-HTML content.
