fix: remove conflicting GPG configuration that breaks passphrase handling

- Remove custom GPG configuration step that was interfering with action
- The crazy-max/ghaction-import-gpg action handles all GPG setup automatically
- Remove GPG_TTY environment variable (not needed)
- Let the action configure GPG agent with proper pinentry mode
