[docs] [issue31533] Dead link in SSLContext.set_ciphers documentation

[Felipe]

New submission from Felipe:

The link to the `OpenSSL cipher list format` 404s. I don't know if it's where the original meant to point, but the same information is available at https://wiki.openssl.org/index.php/Manual:Ciphers(1)#CIPHER_LIST_FORMAT
