feat: update Vercel, Cloudflare, and Netlify adapter major versions

[eltigerchino]

fixes #13314

This PR updates the installed versions of the Vercel, Cloudflare, and Netlify adapters to use their latest versions.

A fresh project created by pnpx sv create using adapter-auto fails on Vercel because it uses Node 22 in build environment but installs an old version of the adapter which is incompatible with Node 22

I wasn't sure about the changeset version or message for this one. Please feel free to correct it.

Is there some sort of test we could add to prevent this in the future? It seems like a hard to thing to remember to update

Good idea. I've added a test that checks if each auto installable adapter uses the latest major.

Great idea with the test!

Thanks to @hyunbinseo who also prepared sveltejs/cli#401 so that the latest version of sv should work out of the box now.
