fix: update badge styles in README for consistency

[Ajimaru]

This pull request updates the badges in the README.md file to provide more relevant information and improve visual consistency. The most important changes include adding new badges for Python and OctoPrint version compatibility, download statistics, and updating the style and links for all badges.

README badge updates:

• Added badges for supported Python versions, OctoPrint compatibility, latest release, download statistics, and a "Made with Love" badge to the top of README.md.
• Updated all badge links to use the correct casing for the repository owner and name, and applied a consistent flat-square style for improved appearance.
• Replaced the old CI badge with a new one that reflects workflow status for the main branch and uses the updated badge style.
• Removed the old GitHub release and CI badges to avoid duplication and ensure all badges are up to date.
