The improvements are pretty minimal and not strictly necessary (except for the formatting). Normally, I would not start a patch for this, but there is already a patch https://review.typo3.org/c/Packages/TYPO3.CMS/+/80599 where I first intended to make more changes (in particular the formatting of the bullet lists), but was deemed as too much.

1. bullet lists should have a newline before and after, otherwise they will not be rendered correctly, see https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/13.0/Breaking-100229-ConvertJSConfirmationToBitSet.html#impact: matches, setValue and isValid is a list

2. \TYPO3\CMS\Core\Type\Bitmask\JSConfirmation::method should be \TYPO3\CMS\Core\Type\Bitmask\JSConfirmation?

3. "calling public methods methods" should be "calling public methods"

4. The part for BackendUserAuthentication->jsConfirmation() in "Affected installations" could be rephrased for "affected installations"
