It would be good for all the links to the WCAG website be updated to the equivalent WCAG 2.2 standard. This came out just [over a year ago now](https://www.w3.org/TR/WCAG22/) and should be the canonical links we provide when giving guidance to developers. There was this issue https://github.com/jsx-eslint/eslint-plugin-jsx-a11y/issues/1008 - however it was more about rules that need to change. I am only suggesting we change our links in the documentation.
