chore: Add release configuration files for automated versioning

- Introduced .release-please-manifest.json to define the initial version.
- Added release-please-config.json to configure release management for the Prometheus Todoist Exporter, specifying package details and changelog types.
- Updated GitHub Actions workflow to utilize the new configuration and manifest files for streamlined release processes.
