Upgrade GraphQL to 8.x.x

[Piedone]

Is your feature request related to a problem? Please describe.

We currently use 7.9.0 of the GraphQL packages. However, as of now, 8.1.0 is out, so we should upgrade.

Describe the solution you'd like

Upgrade to the latest (8.x.x) GraphQL packages. This was started under #16736 but needs to be done for 3.0 since it's breaking.

Furthermore, the ignore in dependabot.yml for GraphQL packages should be removed.

Describe alternatives you've considered

7.9.0 is the last 7.x.x. release, so we need to upgrade to 8.x.x if we want to stay current.
