Links in docs are missing extensions

[runephilosof-abtion]

For instance, the following should be ./1.2-Tools.md

harbor/docs/1.-Harbor-User-Guide.md

Line 401 in fe052ac

You'll find more information and examples in the [Tools guide](./1.2-Tools).

Thanks for the report! the situation with links is mostly because older version of current docs was imported from the GitHub wiki where extension is not needed. There's already automation in place, but it looks like overlooked some links, I'll be updating them to work properly in all locations in one of the upcoming releases.
