Replace tests/functional/manifests/OpenZeppelin with ape dependencies usage

[antazoey]

Describe

We have some hardcoded manifests in Ape's tests for openzeppelin, which are kinda big and nasty.
Let's replace those with Ape's own dependency system.
Now that Ape Test Tests Ape, this makes a lot of sense and should be straighforward.

Specification

Update the config Ape's tests uses (i think it is in tests/ folder?) to include the open zeppelin dependencies.
Reference the manifests from these dependencies using Ape's dependency manager (off the project).

Dependencies

Exactly.
