The "old" way of defining tuples is `[T, U]`, but I think TS 4.7 introduced "named" tuples, which at least provides a little bit of context to consumers, e.g., `[foo: T, bar: U]`. Since a tuple is just a fixed-length array, the names aren't actually used in code, but are surfaced in type information and error messages regardless.
Also:
- Fixed bad param name in definition of `SessionHandler`
- Used a semantically-correct type for `StopScreenRecordOptions.formFields`
yeah this is my bad. if we really need the history I can redo this.
no significant changes; just the usual stuff about builds and types.
bonus: I figured out how to get webdriverio types working
