chore: Publish to NPM with provenance (#91)

The release process in this repository is already automated via
GitHub Actions, which is a great first step toward creating trust in the
supply chain. Recently, NPM has started to support publishing with the
`--provenance` flag. This flag creates a link between the GitHub Actions
run that created the release and the final artifact on NPM. This linkage
further ensures that package installs can be traced back to a specific
code revision.
