ci: fix workflow deployments

[philiplinden]

This pull request updates documentation and refines the CI/CD workflows for changelog generation and mdBook deployment. The main changes include adding a new changelog section for version 0.4.1, improving documentation, and making deployment workflows more robust and targeted.

Documentation and Changelog Updates:

• Added a new section for version 0.4.1 in CHANGELOG.md, summarizing documentation improvements, experimental features, and repository workflow changes.

CI/CD Workflow Improvements:

Deployment Logic:

• Updated the deploy job in .github/workflows/mdbook.yml to only run on pushes to main or when a tag is created, ensuring deployments happen at the right times.
• Removed redundant deployment condition from the Deploy to GitHub Pages step, since it's now handled at the job level.

Changelog Generation:

• Modified the changelog workflow in .github/workflows/changelog.yml to remove the --bump argument, preventing accidental version bumps during changelog generation.
