ADT-449-1: The new build is rather large

[jemmyw]

Shrink the built file by removing as many external dependencies as possible:

• Add test for extractReferenceFromName
• Remove inflected, we only used it to titleize PR state
• Use string graphql queries so that graphql print does not need importing
• Use fetch directly instead of using @octokit/graphql
• Remove moment by replacing the single function it uses

This takes the built gz file from 289kb to 114kb
