Type-safe and tested utility to easily group an array of GraphQL objects by their typename

//#region src/legacyGroupByTypename.ts
/**
* Replaces `Object.groupBy` with a legacy implementation for environments that don't support it.
*
* This is part of the new baseline for 2024 and currently implemented by all major browsers.
* TypeScript support requires 5.4 or later, and should target `ESNext` or upcoming `ES2024`.
* Node support requires Node 21 or later.
