In earlier incarnations of these transformers we used the set of all available providers for tasks such as generating implied provider configuration nodes. However, in modern Terraform we can extract all of the information we need from the configuration itself, and so these transformers weren't actually using this set of provider addresses. These also ended up getting left behind as sets of string rather than sets of addrs.Provider in our earlier refactoring work, which didn't really matter because the result wasn't used anywhere anyway. Rather than updating these to use addrs.Provider instead, I've just removed the unused arguments entirely in the hope of making it easier to see what inputs these transformers use to make their decisions.
