+ * GitHub Actions Core Object Shim
+ *
+ * This module provides a lightweight shim of the @actions/core object for use

+ * When running in GitHub Actions context with @actions/core available, this shim

+ *   core.info("Information message");
+ *   core.warning("Warning message");
+ *   core.error("Error message");
+ *   core.debug("Debug message");
