orgcard: Remove another timeline entry
* doc/orgcard.tex (Filtering and Sparse Trees): Don't mention timeline
because this feature will be removed in version 9.1.
90f87cb98 removed the org-timeline reference in the "Agenda Views"
section but missed this one.
As a bonus, this fixes a column formatting issue in the
orgcard_letter.pdf output (orgcard.pdf was not affected) that was
caused by an extra line added in 4340cc78f.
