Gql

Issue 529 reported that by default the `AIOHTTPTransport` was not validating ssl certificates
(a self-certificate was accepted by default).

This version adds a warning to warn users (See PR 533).

As a workaround, using `ssl=True` in the transport arguments fix the issue.

`graphql-core` has been restricted to `<3.2.4` to fix tests.

A new stable version will be made shortly.

**IMPORTANT**: graphql-core has been reverted to the stable versions 3.2.x
See 427
A new pre-release version will be made shortly with the graphql-core versions 3.3.x
