Move GraphQL-OTEL to the monorepo

Problem

The core of GraphQL Debugger is this directive package maintained by us.

This package has dependencies of open telemetry and GraphQL and it's cumbersome and flaky to maintain and release both separately

Solution

We should move the contents of the graphql-otel package to this mono repo, under the name of @graphql-debugger/trace-directive and then reexport the existing methods back to the existing users of graphql-otel.

It's important we keep ourselves compatible with whoever is using graphql-otel and redirect documentation etc.
