Clarify version number for which the example works
Clarify version number for which the example works

#461 changed option name and in https://github.com/adnanh/webhook/pull/528#issuecomment-826165812, @moorereason suggests to look at old tags of example documentation. This would mean that users have to read through random old documentation to discover why their packaged version doesn't work . Suggesting that clarity in the examples is preferable.

Recall that renaming this doesn't give the user some easy exception. It just mean that the trigger isn't satisfied, so there are A LOT of options for debugging.

(which takes a lot of time to do, so that's why this information is important)
