Use `@tsconfig/node16` instead of custom `tsconfig.json`

[JamieMagee]

Description: Use @tsconfig/node16 instead of a custom tsconfig.json. Equivalent to:

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "display": "Node 16",

  "compilerOptions": {
    "lib": ["es2021"],
    "module": "commonjs",
    "target": "es2021",

    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "moduleResolution": "node"
  }
}

Also required an updated version of TypeScript, to recognise ES2021 as a valid target, and updated version of ncc to recognise the updated TypeScript.
