Align terminology with GraphQL Composite Schemas Working Group Glossary

[jonnydgreen]

Following on from discussions in the GraphQL Composite Schemas Working Group: https://github.com/graphql/composite-schemas-wg it would be good to align terminology.

Current working glossary: graphql/composite-schemas-wg#34

Terms agreed in the inaugural meeting in 14th July 2022:

• Subschema - essentially the schema of a federated service (definition TBD)

Exploration

TODO:

• Explore and identify terminology currently used in Mercurius
• Explore and identify terminology to be updated in Mercurius to align with the WG outcomes

Potential places to look in/look out for:

• Docs
• Mercurius lib
• Examples
• Tests
• File names
