deps: allow updating to openssl 3.1.x
The tag in the new updating script only matches OpenSSL 3.0 releases. There is now 3.1.2 release of OpenSSL-quic (see ref). Update the script to grab any 3.x release of OpenSSL.
Drive-by: update the help message. Refs: https://github.com/quictls/openssl/tree/openssl-3.1.2+quic
