Code Review

This pull request adds aliases to a large number of documentation files under best-practices/ and develop/. The changes are straightforward and help improve navigation and URL stability. My main feedback is to ensure consistency in the alias format, specifically regarding the use of trailing slashes. I've left a few suggestions to make the alias format uniform across all modified files. Overall, this is a good and necessary update for the documentation structure.
