Refactor GitHub Actions workflows for deployment

- Removed the obsolete `deploy.yaml` workflow file.
- Integrated deployment steps into the `main.yaml` workflow, ensuring a streamlined CI/CD process.
- Updated deployment job to trigger after the release job, maintaining necessary permissions and steps for JReleaser deployment.

These changes enhance the organization of workflows and improve the deployment process within the GitHub Actions configuration.
