 * about the definition changes, including documentation. This is the same
 * formula the (now-refactored) `buildWorkerManifestFromRegistry()` used for
 * its `workflowRevision` field before this module existed.

 * ```ts

 * const revision = await deriveWorkflowRevision({ name: 'checkout', workflowVersion: '2.1.0' });
 * console.log(revision.startsWith('sha256:')); // true
