wrong typespec for ExDoc.Language.Elixir.module_data/3 #2117
Description
The ExDoc.Language.Elixir module defines a typespec for module_data/3 that is incorrect.
The language: is defined as ExDoc.Language.Erlang instead of ExDoc.Language.Elixir as returned by the implementation which sets the language: __MODULE__
I suspect this is a copy&paste error.
I'm currently working on something else, but I'm happy to provide a PR soon(ish)
