Update release workflow for version calculation and changelog generation

[sni10]

This pull request updates the release workflow to automate versioning and changelog generation for releases made from the main branch. The workflow now calculates the next version, generates a changelog, creates a new tag, and uses this tag for the GitHub Release. This change streamlines the release process and removes the need to push tags manually.

Release workflow automation:

• The workflow now triggers on pushes to the main branch instead of only on version tags, enabling automated releases from main.
• Adds a step to automatically calculate the next semantic version (bumping the patch version) based on the latest tag, defaulting to v0.1.0 if no tags exist.
• Generates a changelog from the commit history since the previous version tag and prints it to the workflow logs.
• Adds a step to create and push the new version tag automatically.
• Updates the GitHub Release step to use the newly created tag and changelog, ensuring releases are consistent and automated.
