`changeset version` prefixes the first line of every committed changeset
with its commit ("- d18deed: **Lead.** text"), so a changeset that opens
with its bold lead-in, which is the shape the release notes ask for, was
never matched in a changesets-bot release. The pattern now allows that
prefix.
The release notes also put group labels in bold at the start of a line:
"**Fixes.**" and "**Fixes applied while landing.**" (1.41.1, 1.41.0,
1.35.0, 1.33.3). Those were taken as highlights, so a release with few
features announced "... · Fixes applied while landing". They are skipped
like the Thanks block. Tests cover both, and a release with no lead-ins.
