[ruby/openssl] pkey: implement {DH,DSA,RSA}#public_key in Ruby
The low-level API that is used to implement #public_key is deprecated in OpenSSL 3.0. It is actually very simple to implement in another way, using existing methods only, in much shorter code. Let's do it. While we are at it, the documentation is updated to recommend against using #public_key. Now that OpenSSL::PKey::PKey implements public_to_der method, there is no real use case for #public_key in newly written Ruby programs. https://github.com/ruby/openssl/commit/48a6c391ef
