Upgrade website dependencies (#11)

Summary:
- Removed `resolutions` override. This looks to be extraneous.
- Updated specified version ranges for some packages to actually enable
  picking up updates
- Ran upgrade.
- Deduped `yarn.lock` (with `npx yarn-deduplicate yarn.lock`). Yarn
  likes to say this isn't necessary but this sort of cruft can still
  build up, ending up with too many things getting installed and
  parsing/executing more JS than needed.
