fix(jwt/introspection): ability to disable introspection based on JWT result

[ardatan]

Fixes #3614 so you can combine JWT plugin with introspection plugin in this case.

import { useDisableIntrospection } from '@graphql-yoga/plugin-disable-introspection'
import { useJWT } from '@graphql-yoga/plugin-jwt'

const yoga = createYoga({
  // ...
  plugins: [
    useJWT({
      reject: {
        missingToken: false,
        invalidToken: false
      }
    }),
    useDisableIntrospection({
      disableIf(_req, ctx) {
        // If there is no JWT token(unauthorized), disable introspection
        if (!ctx.jwt) {
          return true
        }
        return false
      }
    })
  ]
})

The following changes are needed;

JWT Plugin changes;
Ensure the JWT context has been added before any GraphQL Execution hooks when the plugin is used via Yoga

Introspection plugin changes;
Expose the server context as the second parameter, so introspection can be disabled based on the
context

import { createYoga } from 'graphql-yoga'
import { useDisableIntrospection } from '@graphql-yoga/plugin-disable-introspection'

// Provide your schema
const yoga = createYoga({
  graphiql: false,
  plugins: [
    useDisableIntrospection({
      isDisabled: (_req, ctx) => !ctx.jwt,
    })
  ]
})

const server = createServer(yoga)
server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})
