Outdated link in ARIA19

[JAWS-test]

https://www.w3.org/WAI/WCAG21/Techniques/aria/ARIA19

There are also a number of special case live region roles which can be used instead of applying live region properties directly.

links to https://www.w3.org/WAI/PF/aria-practices/#chobet.
It should link to https://www.w3.org/TR/wai-aria-practices-1.1/

The only problem is that the page does not currently contain any information about Live Regions. But this should be changed (w3c/aria-practices#78).

for simple/unambiguous things like this...why not send a pull request rather than an issue. much easier to action for the maintainers...

sorry, I did not know

I probably don't have the right to do this. It doesn't work

[patrickhlauke]

sorry, it's admittedly non-trivial if you've never done one before...

Hi @patrickhlauke,
Maybe you can help me? I wanted to create different PRs, but I always get all the changes for different PRs inserted into each PR (like in #959 and #912). The problem also occurs when I use different branches locally. I didn't find a hint in the GitHub help how to fix the problem. Many thanks in advance
