Update dependencies

- Update dependencies (except demitasse which requires test changes)
- Fixes eslint & prettier issues
- Add James to the contributors list
- Append `npm install` step in the package.json `update` script
- Add `fix` script to package.json that auto-fixes prettier and eslint
- Add `prettier` script to package.json which includes non-code files
  (e.g. json) that eslint ignores. Also include this in `npm run lint`
  so that PRs will catch prettier issues too.

 ## Roadmap
 
-* [x] Fork non-production polyfill from [tc39/proposal-temporal repo](https://github.com/tc39/proposal-temporal/tree/main/polyfill)
-* [x] Release initial pre-alpha to NPM at [@js-temporal/polyfill](https://www.npmjs.com/package/@js-temporal/polyfill)
-* [x] Sync the code in this repo with the handful of polyfill changes that have recently been made in the [tc39/proposal-temporal](https://github.com/tc39/proposal-temporal) repo
-* [x] Release alpha version to NPM
-* [x] Deprecate all other earlier Temporal polyfills
-* [x] Optimize slow operations by reducing calls to Intl.DateTimeFormat constructor (see #7, #8, #10, #12)
-* [x] Convert to TypeScript for better maintainability
-* [x] Improve typing of sources for better maintainability
-* [ ] Migrate to JSBI for improved compile-time safety around BigInt operations.
-* [ ] Optimize performance of other slow operations
-* [ ] Release production version to NPM
