Description

This pull request updates the release automation and changelog generation to improve integration with GitHub and simplify configuration. The main changes include adding explicit GitHub repository information to cliff.toml, updating the changelog template to use GitHub-specific commit metadata, and refining workflow arguments.

Changelog and Release Automation Improvements:

• Added a [remote.github] section to cliff.toml with the repository owner and name, enabling better GitHub integration for changelog generation.
• Updated the changelog template in cliff.toml to use commit.github.pr_number and commit.github.username instead of the generic commit.remote fields, ensuring more accurate pull request and author links.
• Modified the git-cliff-action step in .github/workflows/release.yml to pass the --github-repo argument directly, streamlining repository context handling.

Configuration Simplification:

• Removed the custom commit-message prefixes for dependencies and GitHub Actions updates from .github/dependabot.yml, simplifying Dependabot configuration. [1] [2]
