language support for @oneOf

[acao]

Resolves #3678

Requires reverting #3682

• switch devDependecies to use graphql@16.9.0 for full @oneOf support
• diagnostics support - I can't seem to get the rule to work :( - caused by upgrade to graphql v17 including support for new incremental delivery format #3682
• autocompletion support - works in unit tests, but not yet in graphiql because of upgrade to graphql v17 including support for new incremental delivery format #3682
• hover support
• fix all unit tests failures caused by adding a new input type to the test schema

Thanks for working on this. Since the last push was 10 months ago, would it make sense to rebase this against latest changes? Also, the RFC is accepted, see comment
