Standardize OTEL GraphQL Attributes

[danstarns]

• OpenTelemetry Epic #8

Problem

The current GraphQL semantic conventions support very few attribute values that GraphQL Dugugger uses to power its engine.

We currently append and process a collection of attribute values listed here in the graphql-otel package.

We should work with the community to standardize these conventions so that GraphQL Debugger is compatible and extensible.
