See the attached patch with tentative changes to the manual.
Let me know if you think that things are still not clear.

Subject: [PATCH] org-manual: Clarify auto-detection of code block result type

* doc/org-manual.org (How to evaluate source code): Link to Results of
evaluation section for details about the inserted code block result.
(Type): Clarify that auto-detecting result type relies on specific
language backend, linking to the relevant manual section.
(Languages): Clarify that Worg is a website.
