Renovate workflow fails with “No repositories found” despite checkout #195

Description

The current Renovate GitHub Actions workflow is failing because Renovate is not detecting any repositories to process. During execution, the workflow produces the warning:

WARN: No repositories found - did you want to run with flag --autodiscover?

This occurs because Renovate does not automatically detect the repository when run via the GitHub Action. To resolve this, we need to explicitly specify the repository Renovate should operate on by adding:

env:
  RENOVATE_REPOSITORIES: "CCPBioSim/CodeEntropy"
