Move to pathe to support working in environments without "path"

[Mkassabov]

What this does

Drops import of path in favor of unjs/pathe

Why

path might not exist in all environments (in our specific case cloudflare workers). pathe is a drop in replacement for path that works in all environments.

also fixes this not working in build pipelines that rely on prefixing for native deps (node:path).
