I think the settings on the Vercel side need to be corrected.

It seems Vercel doesn't allow the use of use-node-version for some reason.

Would the engines and pnpm.executionEnv.nodeVersion serve the same purpose?

I think it's possible.
Change this from the original.

🤔

I tried deploying it with a Vercel account, but it passed normally...
I wonder what it is...

 ERR_PNPM_INVALID_NODE_VERSION  "~22" is not a valid Node.js version

Maybe an exact version is needed🤔

[L4Ph]

Apparently there is no way to specify the node version in Vercel. (Also, it seems that it is not possible to make only Vercel be ignored.)

The commit has become too dirty, so I'll clean up the commit and submit another pull request.
