Shorten remaining over-wide docstrings

* lisp/ob-latex.el (org-babel-latex-begin-env):
(org-babel-latex-pdf-svg-process): Shorten docstring to under 80
characters.
* lisp/org-plot.el (org-plot/preset-plot-types): Fill long lines and
add two spaces after periods.

With Emacs 28.0.50 the byte-compiler now warns about docstrings that
are too wide.  The recent ports from the Emacs repo covered all of the
cases that have already made their way to the Emacs tree.
