Fix dead links that use the DISTRO macro

After introducing the DISTRO_LATEST_TAG and DISTRO_REL_LATEST_TAG
macros, use them in links that currently use DISTRO/DISTRO_REL_TAG. When
building for the tip of a branch, this will replace the current A.B.999
in links to the latest existing tag.

The links were found across the documentation by running 'grep -r
"http.*5\.2\.999"' inside the _build/html output after building the
docs.
