* Update GraphQL parser
Fixes#3601
This adds support for
- description as strings
- extending all the possible types
- block strings
- allow removing {} if there's no implementation for all graphql types
This is a breaking change but shouldn't be a big issue.
- Empty types are no longer allowed (there's an option to enable it but it hasn't been released yet). The fix is to remove `{}`
Something that hasn't been changed because not released:
- Doesn't support the new `&` separator for implementing multiple interfaces
A bug has been fixed:
- Now properly prints @directives for unions.
* Properly handle triple quotes
