[mod] hex engine: normalize (some of) the linked terms

The names of the links are rather tags than real names, and they sometimes vary
greatly in their spelling:

- GitHub: github, Github
- Source code: Repository, SCM, Project Source Code
- Documentation: docs, Documentation

It was standardized to terms such as 'Source code' and 'Documentation', as
translations already exist for these terms.
