GitHub Actions for Automated Nightly and Official Releases

[renxida]

Overview

This PR refactors our GitHub Actions workflows to implement a new release strategy. The new approach automates the creation of nightly releases and simplifies the process of creating official releases.

Changes

1. New Workflow: Nightly Releases (nightly-release.yml)

• Automatically creates a nightly release on every push to the main branch and on every pull request.
• Generates a version number in the format X.Y.Z-nightly.{run_number}.
• Creates a GitHub pre-release with the nightly version tag.

2. Modified Workflow: Official Releases (release.yml)

• Updated to automatically select the latest nightly release when triggered.
• Removes the need for manual input of the nightly release tag.
• Creates an official release based on the latest nightly, updating version numbers in files.

3. Modified Workflow: Package Publishing (publish.yml)

• Now triggers only on official release tags (v*..).
• Publishes the package to PyPI when an official release is created.

Benefits

1. Automated Nightly Builds: Provides easy access to the latest changes for testing.
2. Simplified Release Process: Official releases can be created with a single click, without manual version selection.
3. Consistent Versioning: Ensures a clear progression from nightly to official releases.
4. Automated Publishing: Reduces manual steps in the release process.
