Add releases to GitHub

It solely handles release metadata like titles and tags, avoiding bloat from asset bundling, which simplifies configuration and reduces overhead in CI/CD pipelines.

Includes built-in compatibility for self-hosted instances via GH_HOST and GH_ENTERPRISE_TOKEN environment variables, as noted in the README, making it versatile for corporate environments.

Allows overriding default tags with custom values, enabling tailored versioning schemes without being tied to Git tag triggers.

Supports marking releases as prereleases with a simple boolean flag, facilitating testing and staging workflows directly from automation.

Works with standard GITHUB_TOKEN or enterprise tokens, and the README provides clear guidance on permission setup, easing integration into existing GitHub Actions.
