docs: map npm package links to npmx.dev (#661)

- [x] Update `[npm-url]` reference link from
`https://npmjs.org/package/urllib` to `https://npmx.dev/package/urllib`
in README.md
- [x] Update `[download-url]` reference link from
`https://npmjs.org/package/urllib` to `https://npmx.dev/package/urllib`
in README.md
- [x] Update example URL from `https://www.npmjs.com/package/urllib` to
`https://npmx.dev/package/urllib` in README.md
- [x] Run `pnpm dedupe` to fix duplicate dependencies in lockfile (fixes
`vp dedupe --check` CI failure)
- [x] Remove invalid `ts-equals-import` group from
`experimentalSortImports` in `vite.config.ts` (not a valid group name in
newer oxfmt)
