The fix is good and should be applied.

However, if viewed strictly, that `Link text <https://url/>`_ syntax is only required if the link text and the url are different.

So in this case you could (or the original author) just use a simple url without any additional syntax.

However, better still would be if we did something like this to put the links inline in the text:

However, the fix is better than a broken link so:
