I noted there is a typo at "rsa_pkcs1_sha5256".
Fix this typo, SSL_CTX_set1_sigalgs_list works as expected.

I’m using SSL_CTX_set1_sigalgs_list to set my favorite signature algorithm.
But there is more algorithm listed on client hello message than I desired.

Using wireshark, we can see the following signature algorithms are offered
