This PR builds on #1048, so you should see the diff from that PR:

https://github.com/benjie/graphql-spec/compare/asterisk...benjie:graphql-spec:no-null-bubbling

This introduces a directive on operations that disables the null/error propagation behavior by treating all Non-Null types as if they were Null-Only-On-Error types (see #1048).

The specific name of this directive (currently @nullOnError) is open to workshopping:

• @noBubblesPlz 😉 or @tepid 🤣
• @disableNullPropagation / @disableErrorPropagation / @noNullPropagation / @noPropagation / etc
• @localErrors
• @dontHandleErrorsForMeIKnowWhatImDoing
• {your suggestion here}

This PR currently only includes a description of the directive and an example; the implementation is yet to come (hence: draft).
