Replace path dependency with node:path

[boehs]

✘ [ERROR] Could not resolve "path"

    ../node_modules/.pnpm/@[email protected][email protected]/node_modules/@elysiajs/swagger/dist/index.mjs:277:17:
      277 │ import path from "path";
          ╵                  ~~~~~~

  The package "path" wasn't found on the file system but is built into node. Are you trying to
  bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

per https://developers.cloudflare.com/workers/runtime-apis/nodejs/

Node.js APIs are available under the node: prefix, and this prefix must be used when importing modules, both in your code and the npm packages you depend on.
