Links within docs should use xref's instead of direct links

### What You Are Seeing?

The Algolia indexing crawl is resulting in a number of pages being ignored because they are redirects. Further investigation found that these are all links in the style of `https://docs.chocolatey.org/en-us/features/package-reducer` instead of ``.

### What is Expected?

There shouldn't be ignored results if possible. We should be using xrefs when cross linking.

### How Did You Get This To Happen? (Steps to Reproduce)

Just let the Algolia index crawl happen.

### Additional details

While this was discovered with the Algolia search, searching for `https://docs.chocolatey.org` in the repo can help identify locations that are not using xrefs.
