A co-worker pointed out that guys also have new links as well, thanks to them I was able to find the new documentation pages.
To point out, this is the link for the installation page that is still available coming from the Docs navigation from Strapi(dot)io’s landing page – https://strapi.io/documentation/developer-docs/latest/getting-started/installation.html
While this is the new and correct installation page link: Installation - Strapi Developer Documentation
