fix: keep all of a PR's changesets in the release PR summary

The changeset release PR summary deduplicated entries by PR number, so
a PR that ships more than one changeset had every entry after the first
dropped from the summary (they stayed only in the raw output). Key the
dedup on entry content instead, which keeps distinct changesets from the
same PR while still collapsing one changeset repeated across package
sections.
