docs: corrects deprecation warning for waitForDomChange

[egilsster]

What:

If you are migrating from waitForDomChanges, it suggests using wait instead, which is also deprecated and it suggests waitFor. The link in this particular warning is linked to waitFor.

`waitForElement` has been deprecated. Use a `find*` query ...

`waitForDomChange` has been deprecated. Use `wait` instead ...

but then it says wait is also deprecated:

`wait` has been deprecated and replaced by `waitFor` instead. In most cases you should be able to find/replace `wait` with `waitFor`.

Why:

☝️

How:

Updated deprecation warning string with the correct suggestion
