[ruby/openssl] digest: use EVP_MD_CTX_get0_md() instead of EVP_MD_CTX_md() if exists
The function was renamed in OpenSSL 3.0 due to the change of the lifetime of EVP_MD objects. They are no longer necessarily statically allocated and can be reference-counted -- when an EVP_MD_CTX is free'd, the associated EVP_MD can also become inaccessible. Currently Ruby/OpenSSL only handles builtin algorithms, so no special handling is needed except for adapting to the rename.
