gleam: Detect tests using `describe` API for Startest (#12221)

Marshall Bowers created 2 years ago

This PR updates the Gleam runnables to detect tests using the `describe`
API in Startest.

This isn't entirely functional yet, as it is still just uses the test
function name to run the tests (which Startest doesn't yet support).

Release Notes:

- N/A
