Project Vouches jrossi as Contributor

The trigger.dev project has officially vouched jrossi as a contributor. This addition to the VOUCHED.td file grants jrossi commit access to the repository, allowing direct pushes to the main codebase.

The vouch process is a standard security practice in open source projects — it ensures that only trusted individuals can contribute directly, helping maintain code quality and security standards.

This change affects the project's contributor management in the .github directory.
