[patch] ox-latex.el: add `:options' LaTeX attribute to tables

Hi,

The `:options' attr. allows adding an optional argument with various
table options (between brackets in LaTeX export), since certain tabular
environments, such as `longtblr' of the `tabularray' LaTeX package,
provides this structure (see:
https://list.orgmode.org/CALtzAB1yM+uG_xHghCxTLRX5mgbzNvT5+PO=DuaBB28nCsVqEA@mail.gmail.com/#r)

Example:

#+ATTR_LATEX: :environment longtblr
#+ATTR_LATEX: :align colspec = {XXX}, width = 0.85\linewidth
#+ATTR_LATEX: :options remark{Note} = {Lorem ipsum dolor sit amet}

==> \begin{longtblr}[remark{Note} = {Lorem ipsum dolor sit amet}]{colspec = {XXX}, width = 0.85\linewidth}

Best regards,

Juan Manuel
