Fixes: #3981
Earlier, the typings for the waitFor commands were very restrictive due to which the formats which worked in JS were not working in TS.
This PR makes the types for the waitFor commands lenient so that everything that works in JS continues to work in TS, but at the added expense of not at all strict typings which could be error-prone for users (though the argument names have been constructed in a way to reduce this).
Other solution to this would have been to create an overload corresponding to every way the command can be used, but that would have led to way too many overloads for each waitFor command and would have been hard to manage.
