fix(org-latex): inhibit-modification-hooks in auto-tabularx to prevent recursion

Browse Source 
The insert call in my/org-auto-tabularx triggered buffer-change hooks (e.g.
org-element-cache) during LaTeX export, causing infinite recursion and
'max-lisp-eval-depth exceeded'. HTML export was unaffected (hook only runs
for latex backend). Fix: wrap body in (let ((inhibit-modification-hooks t))).
