nested-interactive: Improve failure description and fix message for nested checkboxes

[iamrafan]

The example below seems to work well with all the screen readers but it is in accessible using Dragon. When I command Dragon to click the checkbox, I see Dragon showing multiple options to select from despite only one checkbox being visible on the screen.

GIF showing the experience with Dragon:

Product: axe-core

Expectation: Show appropriate Failure description and Fix the following messages

Actual: The failure description only states the nested element is not available to screen readers

Motivation: This would be an issue for Speech recognition software users as they would not be sure which number to select to be able to click on the checkbox.

axe-core version: 4.3.3

Verified with the latest dev branch code,
for nested-interactive rule, failure description has changed, and now its describing as
"Ensures interactive controls are not nested as they are not always announced by screen readers or can cause focus problems for assistive technologies"
