Add a “Related Guides” section at the end of each article

[gorse-choral]

Description

The documentation is helpful, but after reading a guide, users don’t always know where to go next. A “Related Guides” section could help users find more relevant content easily.
Once users finish reading a guide, they might not know what other related topics to explore. This can cause them to miss out on valuable information or resources.

Proposed Solution

Add a “Related Guides” section at the end of each article with links to other relevant pages in the documentation.
