AI Summary: Automate the creation of pull requests to update four Layer5 Academy repositories (layer5-academy, exoscale-academy, academy-build, academy-example) whenever a new release of the academy-theme Hugo module is made. This will involve adapting an existing GitHub workflow from the Sistent project to handle the updates and testing the automated PR creation process.
