🔧 Add Vue documentation and make package public

[mormubis]

Motivation

Same idea as #4384 for Next.js. The Vue package needs docs before we publish it in beta, and it's still marked as private. This would be removed to point to the Docs page when we have it uploaded.

Changes

Update rum-vue README.md with setup instructions, router view tracking, and error reporting.
Add version tag and remove "private": true in package.json.

What happened to the error tracking part?

nit for next PR. I would also add "In your main.ts (or main.js)" here.
