docs: update lockfiles to resolve lodash and tar vulnerabilities (#1013)

## Summary
- Updates `yarn.lock` files using `yarn up -R` to pull in patched
versions:
  - lodash 4.17.23 (fixes GHSA-xxjr-mmjv-4gpg, medium severity)
  - tar 7.5.7 (in website)
- No new resolutions needed - semver ranges allow the patched versions

## Test plan
- [x] `yarn npm audit --all` shows only deprecation warnings (no
security issues)
- [ ] CI passes
