Fixes #23075 In OpenSSL 3.2 EVP_DigestSign and EVP_DigestVerify were changed so that a flag is set once these functions do a one-shot sign or verify operation. This PR updates the documentation to match the behaviour. Investigations showed that prior to 3.2 different key type behaved differently if multiple calls were done. By accident X25519 and X448 would produce the same signature, but ECDSA and RSA remembered the digest state between calls, so the signature was different when multiple calls were done. Because of this undefined behaviour something needed to be done, so keeping the 'only allow it to be called once' behaviour seems a reasonable approach.
