(core) Upgrade friendly-traceback and its dependencies

Summary:
Upgrading the friendly-traceback package to include a fix that I specifically requested in https://github.com/friendly-traceback/friendly-traceback/issues/144 as a solution for the problem mentioned in https://grist.quip.com/HoSmAlvFax0j#MbTADAEcJb7 . Specifically, this shows a friendly explanation when using `len()` with a generator expression.

Also upgraded the dependencies `executing` and `stack_data` (which are mine) while I'm at it, although I don't expect this to really change anything.

Test Plan:
Existing tests. There was one test failure because of a new explanation about generic `Exception`s which I've suppressed.

Tested manually that the new explanation appears:
