dataTestId and dataTestPrefixId props are un-intuitive

[mkarajohn]

We should be able to just pass data-testid, which is the common convention (along with permutations data-testId, data-testID and data-testiD which are all valid attributes when using ...byTestId() in testing-library)

dataTestId is unintuitive and some components do not even expose it as an available prop (for example Button)

dataTestPrefixId is even worse, since the order of the words does not even make sense (it should be dataTestIdPrefix)

Since test-id prefixes are not a convention (so there is no reason to use something like data-testid-prefix) I simply sugggest we shorten the prop name to something like testIdPrefix (drop the data part so that one does not assume that since a dataTestIdPrefix exists a dataTestId exists as well)
