I would be great if when tape((<cursor>)) it would be able to drill in the tape.TestCase and show the signature of the callback. 🌷

This is probably on tsc, but let's start here. 😄

Research direction

Start by investigating the tsc signature-help behavior described in the issue, using the tape(()) and tape.TestCase callback example as the reproduction. Done means signature help displays the callback using function type shorthand and drills into the tape.TestCase type as requested.
