It's not clear what in the grammar allows that, but it's clearly allowed since it is used in top-repos.

In #353, adding `_parenthesized_type` caused new parse failures where the parser now resolved away from `tuple_type` too early. Specifically, when parsing an expression like `[(any Foo) ...`, the `tuple_type` interpretation must still be valid at that point in the expression in case we're about to see a `?`. The truly robust thing to do would be to support `$.tuple_type` as the target of the navigation expression. However, this leads to a large number of additional parse failures, as seen in #360. To avoid all of that, we add support in the opposite direction: allow `tuple_type` to be resolved using `_parenthesized_type`, so that the parser seeing the latter does not cause it to invalidate the former.
