[O] [PATCH] doc/Makefile: Auto-generate org-version.tex for orgcard

[Kyle Meyer]

Hello,

It seems that the only place where we hardcode the Org version is
orgcard.tex.  Any objections to auto-generating this as well?

-- >8 --
* doc/Makefile: Add rule to generate org-version.tex.
* doc/orgcard.tex: Include org-version.tex rather than explicitly
setting version and year.

This removes the only instance in the repo where the Org version is
hardcoded.
