This pull request updates the GPG keyname configured within the GitHub Actions resources. This is a routine maintenance task to ensure the continuous and secure operation of automated processes that rely on GPG for signing, such as artifact releases or code verification.

Code Review

This pull request updates the GPG key name in the Maven settings file for GitHub Actions. My review suggests an improvement to enhance security and maintainability by externalizing the GPG key name into an environment variable, similar to how the passphrase is handled. This would prevent hardcoding configuration values and make key management more flexible.
