Changelog: drop the per-CVE listing from the 153.1.0 entry

Fifty-two CVEs broken out by severity, one linked bullet each, ran to sixty
lines and buried the rest of the entry. The summary paragraph keeps the count,
the severity breakdown and the link to MFSA 2026-77, which is a better place to
read the full list than a copy of it here.

Only the 153.1.0 entry changes. Older entries keep their listings: that is what
those releases actually published, and rewriting them would misrepresent them.
releases going forward no longer generate the listing at all.

The published GitHub release body for 153.1.0 was edited to match.

 🛡️ Addressed 52 CVEs from [Mozilla Foundation Security Advisory 2026-77](https://www.mozilla.org/en-US/security/advisories/mfsa2026-77/) (August 18, 2026). This one's mostly patching holes; 19 high, 23 moderate, and 10 low severity CVEs squashed, nothing screaming louder than the rest but the high count alone is enough to not sit on this. Update when you get a sec.
