Add tip to Overly Cumbersome Requirements UWC (#296)

Add tip to Overly Cumbersome Requiements UWC

We get a lot of reports for achievements like "Get the MacGuffin without eating cheese" where the reported flags this UWC with a comment like, "In order to accomplish doing this without getting cheese, the player has to do *big list of steps they didn't find to be obvious*'."

This is an attempt to mitigate that kind of thing.
