[examples] Fix ERR_PNPM_OUTDATED_LOCKFILE when deploying SvelteKit example (#10984)

Currently, [the SvelteKit (v1)](https://vercel.com/new/clone?b=main&s=https%3A%2F%2Fgithub.com%2Fvercel%2Fvercel%2Ftree%2Fmain%2Fexamples%2Fsveltekit-1&showOptionalTeamCreation=false&template=sveltekit-1&teamCreateStatus=hidden) example fails with:
```
ERR_PNPM_OUTDATED_LOCKFILE  Cannot install with "frozen-lockfile" because pnpm-lock.yaml is not up to date with package.json
```

This fixes the lockfile, and therefore fixes the example.

---

As a side-quest, I also fixed the "unmet peer" warnings:
```

  ├── ✕ unmet peer prettier@^2.7.0: found 2.6.2
  └─┬ eslint-plugin-unicorn 43.0.2
    └── ✕ unmet peer eslint@>=8.18.0: found 8.14.0
```
