manuals: replace unnecessary uses of 'yocto_docs' by internal references

These :yocto_docs: references were making external references
to another section of the manual, using the https://docs.yoctoproject.org
website. It's actually better to use internal references (:doc: for an
entire document, and :ref: for a specific section, as they will cause
an error in Sphinx if one day they are no longer valid.
