AST classes Breaking changes in graphql-core 3.3.0a12

[leszekhanusz]

Since the latest graphql-core version (3.3.0a12), tests are failing with gql.

I believe the PR #256 is causing breaking changes in gql by making all the AST classes read-only and without good default values.

Here is the mypy output of gql showing the problems:
