Description
This section suggests main can only have 3 different types:
I think main : List String → IO Unit is a 4th alternative, which lean seems to accept just fine.
Not a terribly important point, but I was confused as to why that wouldn't be allowed. Would be good to clarify.

Research direction
Open hello-world/summary.md at the linked lines and compare the documented main types with Lean's accepted forms. Clarify that main : List String → IO Unit is also accepted, then verify the surrounding explanation still reads consistently. Done means the documentation no longer implies only three valid types.
