ci: use manylinux 2.28 for building pre-built binaries

[adsharma]

Fixes: #199

• Supports glibc-2.28 (wider compat with old distros)
• Supports C++20 and std::format via gcc-13
• Links in libstdc++ statically. Binaries are 5MB larger

This is a good trade off for many of our users. Please reuse pre-built binaries for language bindings, since replicating this is hard and hard to maintain for every language binding.
