Add release notes page, nav entry, changelog entry, and release-notes table cell for the TinyMCE 7.9.3 security patch release covering TINY-14357, TINY-14353, and TINY-14333. CVE IDs, release date, and credits are placeholders pending assignment.
- GHSA-vg35-5wq7-3x7w: Aymane MAZGUITI and Ange Primiterra - GHSA-v98h-vmpc-fpqv: Ivan Babenko (he1d3n) - GHSA-q742-qvgc-gc2f: Tadi Kadango (pending permission)
The GHSA-q742-qvgc-gc2f advisory credits both Tadi Kadango and Ivan Babenko, but the pending credit comment only listed Tadi Kadango.
The advisory for the nested SVG sanitization bypass was published but never documented in the 7.1 release notes or changelog. Add the security fix entry and credit maple3142 of DEVCORE.
