fix: pin compatible release tooling (#8)

Pins semantic-release, the conventional-commits preset, and the exec
plugin to compatible versions so release-note generation no longer
combines the preset requiring conventional-changelog-writer 9 with
semantic-release's writer 8. A dry run against main successfully
generates the pending 1.2.1 release notes.
