Setup release-plan

[NullVoxPopuli]

whenever we're ready for 1.0, this is the tool that'll help us get there.

Just the same, we can use this tool to release minor versions as well!

See: https://github.com/starbeamjs/esyes/pull/4

What's release-plan?

A hybrid of the best parts of release-it and changesets.

Repo / docs here: https://github.com/embroider-build/release-plan

This allows folks with GH Maintainer access to preview and release to npm without actually needing to have any keys locally on their machine (or access to the npm package, which makes management of the repo separate from the npm package easy and encouraged).

• Everything is automated via GH Action workflows.
• We release by merging the "prepare release" preview PR.
• Changelog entries are determined by labels on the PRs (see release-plan readme)
  • we edit the changelog text via editing the PR title

See the newly added RELEASE.md for details.
