ci(docs): Trigger vendure-io update after docs publish

Add a new job that sends a repository_dispatch event to vendurehq/vendure-io
after the @vendure/docs package is published. This allows the docs site to
automatically update when new documentation is published.

- Generate version before publish to capture it as job output
- Use CI bot GitHub App for cross-repo authentication
- Send package version and commit SHA in dispatch payload
