Improve borgmatic version handling and fix deprecated options

- Rename templates to version-based naming (config_1.7.yaml.j2)
- Use command module instead of shell for version detection
- Add check_mode: false for version detection task
- Fix deprecated remote_rate_limit → upload_rate_limit for 1.8+
