delegates type t() to Tast.t()

[marcdel]

this is kind of silly, but i ran into a typespec error on a function that returns a Task when i aliased OpentelemetryProcessPropagator.Task.

Unknown type: OpentelemetryProcessPropagator.Task.t/0.

also, seems like dialyzer is unhappy on main, but i don't understand the issue.

i can test this change locally, but i don't remember how to reference my fork in another project. iirc it's a little different because they're subprojects or w/e?
