There are dozens of instrumentations in this repo, written at different times by different people.
Few different patterns emerged on how to handle the config object in Instrumentation constructor. This PR aims to introduce a common pattern to have consistency across the repo.

This PR aligns all the instrumentations to use:

  constructor(config: FooInstrumentationConfig = {}) {
    super('@opentelemetry/instrumentation-foo', VERSION, config);
  }

After open-telemetry/opentelemetry-js#4659 lands, we can introduce even more consistency and cleanups on the handling of config in instrumentations.
This PR only targets the constructor and super invocation usage

I removed it because GraphQLInstrumentationConfig already extends InstrumentationConfig so it was redundant

This is another bit we may want to align, which is the way we type config in our instrumentations. Here we use the override keyword so we tell typescript to treat the property as an AwsLambdaInstrumentationConfig type. And in other instrumentations we have a getter that casts the config property to the type we need

getConfig(): AwsLambdaInstrumentationConfig {
  return this._config as AwsLambdaInstrumentationConfig;
}

Should we encourage one over he other?

Once open-telemetry/opentelemetry-js#4659 lands, we can cleanup all the config handling variations as the base class would already be typed correctly. Eager to apply this cleanup in all contrib instrumentations

Looks like we are just missing Mongoose and Koa, feel free to grab this commit if it's easiest. Otherwise this looks good.

I'll re-run that test. I can't see how this PR would ahve caused it.
