move from conventional-commits to changesets

[turadg]

What is the Problem Being Solved?

We had some trouble with tags on conventional commits. And a recent PR was merged with commits that weren't "conventional" so the features they introduced weren't picked up in the Lerna publish tooling.

We can manually edit the changelog, but the presence of feat: commits also affects the package version number and the git tags produced, which are cumbersome to correct.
