Remove eslint-plugin-graphql

[BPScott]

Description

Fixes #327. Fixes #320.
Part of https://github.com/Shopify/web/issues/55503.

eslint-plugin-graphql is outdated and unsupported. Consumers should use
@graphql-eslint/eslint-plugin to lint their graphql files.

I am choosing to remove eslint-plugin-graphql without replacement because graphql linting has a large install footprint, and we should not burden consumers that do not use graphql with having to install those additional dependencies.

Upon updating to v42, consumers that currently extend from plugin:@shopify/graphql can instead add the following to their eslint config:

{
plugins: ['eslint-plugin-graphql']},
overrides: [
    {
      parser: '@babel/eslint-parser',
      files: ['*.graphql'],
      rules: {
        'graphql/capitalized-type-name': 'off',
        'graphql/named-operations': ['error', {env: 'literal'}],
        'graphql/no-deprecated-fields': ['error', {env: 'literal'}],
        'graphql/template-strings': ['error', {env: 'literal'}],
        'graphql/required-fields': ['error', {env: 'literal', requiredFields: ['id']}],
      },
    },
  ]
}

This PR:

• Removes the graphql config. Extending from plugin:@shopify/graphql will cause an error as that config no longer exists.
• Removes the dependency on eslint-plugin-graphql
