docs: replace anchor links

Anchor links are treated by Sphinx as external links and are not checked
during build, meaning it is impossible to know if a link becomes broken or
not.

As a matter of fact, most of the anchor links replaced in this commit
were actually broken.

The README now states that anchor links are forbidden so that there's no
need to go through such a change later on.
