when launching the new docs site, we want to have the pricing and homepage in the docs and not in the platform anymore.

• [ ] create multi currency prices in stripe to support pricing based on region
• [ ] create auth redirect route that can be used on the pricing page
• [x] use correct pricing in the pricing widget
• [x] pricing pages: change back from xyflow pro to react flow pro
• [x] pricing pages: check content and texts
• [x] pricing pages: use correct links
