Remove duplicate platform listing from standalone binaries

The platform information was duplicating what's already in the package
manager section and isn't needed in the standalone binaries section.

Changes:
- Remove platform bullet list from standalone binaries section
- Keep GitHub Releases link and go straight to installation examples
- Platform information is already covered in package manager section
