test(deps): add missing requests test dependency
test(deps): add missing requests test dependency

Follow up to #63

When GitHub Actions installs the `poetry` dependency, the `requests`
package comes along.
But in a local env if you haven't installed poetry inside the virtual
environment, the async tests will fail due to starlette using `requests`
as part of their test client.
