Fix broken references in docs

After commit "docs: update the docs to follow new version" references in web documentation under LLamaContext node are not valid (404 file not found). Fix this

Thanks for this. The docs have fallen behind a bit due to the pace of updates in the last few updates, definitely some fixes needed there!

Thank you so much for this contribution! There's an index file to specify the location of the markdown documents, could you please help to update them since you renamed some files?

It looks like this file was changed in commit "docs: update the docs to follow new version" without changing the real location of MD files. That's why I renamed them to reflect the changes in mkdocs.yml. After this PR the path to MD files should be consistent with the content of mkdocs.yml

Sorry I didn't notice that before. Now all thing looks good! :)
