chore: Add pkg.pr.new to preview PRs outside of NPM (#625)

* chore: Add pkg.pr.new to preview PRs outside of NPM

* chore: Try and enable it on maintainer commits

* chore: Build package before preview publishing

* chore: Reduce workflow name verbosity

* chore: Set the version to preview with Git SHA

* chore: Fix Git SHA to use head of PR rather than merge

To be consistent with pkg.pr.new's versioning.
