Subject: [PATCH] ci: Wait for npm before dispatching, and skip releases for
 workflow-only changes

npm can take several minutes to make a new version available (models-ts
1.0.8 took 12 minutes). The dispatched repositories install @latest
straight away, so they could pick up the previous version. Wait until
the new version can be fetched before dispatching, as data-models does.

A merge that only changes files under .github does not change the
package, so the publish workflow no longer runs for it. Pull request
checks are unaffected.
