[bug#66148] [PATCH v2 2/2] doc: Mention it when we were pulled.

[Tobias Geerinckx-Rice]

Now that we use the latest release VERSION even for pulled Guixes,
make it abundantly clear that this is a later build.

* guix/self.scm (info-manual): @set the PULLED flag in version.texi.
* doc/guix.texi (Top): Honour it.
