Datasette-graphql

- Fixes broken demo links in the README. [86](https://github.com/simonw/datasette-graphql/issues/86)

- Upgraded to [Graphene 3.0](https://github.com/graphql-python/graphene/wiki/v3-release-notes). ([#80](https://github.com/simonw/datasette-graphql/issues/80)). This introduces some small backwards-compatibility breaks, hence the 2.0 version number on this release. Most notably, tables or columns that are named after Python keywords (such as `if`) will now be represented in GraphQL with a trailing underscore, `if_`. `description` is also renamed to `description_`.
- Upgraded bundled version of GraphiQL to 1.5.1, running on React 17.0.2. ([75](https://github.com/simonw/datasette-graphql/issues/75))
- Fixed an error caused by tables that include foreign key references to other tables that do not exist. ([79](https://github.com/simonw/datasette-graphql/issues/79))
- Now tested against Python 3.10. ([82](https://github.com/simonw/datasette-graphql/issues/82))

- Now uses the `datasette.client` mechanism for internal calls. [61](https://github.com/simonw/datasette-graphql/issues/61)
- Depends on datasette>=0.58.1

- Fix broken tests against Datasette 0.54. [71](https://github.com/simonw/datasette-graphql/issues/71)
- Bundle JavaScript and CSS assets for GraphiQL, instead of loading them from a CDN. [73](https://github.com/simonw/datasette-graphql/issues/73)
- Pin to graphene dependency < 3.0. [72](https://github.com/simonw/datasette-graphql/issues/72)

- Fixed bug where `in:` and `notin:` filters raised an error when run against lists of integers rather than lists of strings. 68

- Suggested queries for tables (available from the table actions cog menu) now include foreign key expansions. 67
