Provide `GraphQLContext` and `ResolveInfo` in Federated Entity Resolvers

[Maxwell2022]

Firstly just wanted to acknowledge the great work that was done recently to push for Federation 2 support and Federated tracing! 🙏👏

Describe the bug

It seems the GraphQLContext and the ResolveInfo are not injected in the Entity resolver for federated graphs.

Expected behavior/Solution

According to Apollo Documentation (Apollo Server), the Entity resolver should receive few arguments along side the entity representation.

Steps to reproduce

• Only representations is injected in BatchEntityResolver->_invoke()
• Only representations is injected in EntityResolver->_invoke()

Lighthouse Version

latest master branch

[spawnia]

Please refrain from calling missing features bugs or categorizing them as such. According to the Lighthouse documentation, entity resolvers only receive a single argument:

• https://lighthouse-php.com/master/federation/reference-resolvers.html#single-entity-resolvers
• https://lighthouse-php.com/master/federation/reference-resolvers.html#batched-entity-resolvers

This has worked fine so far, what you are asking for is an additional feature.

It seems like a reasonable addition to provide this readily available information and behave more similar to Apollo. I am open to pull requests.
