[deps] bump jruby-openssl to 0.16.3 - #9726

Only includes BC 1.86 bump, gem is smaller by more than 3MB due spliting:

BC 1.86 is smaller mainly because the distribution was modularized, not because cryptographic functionality disappeared.
In the jars used here:

• bcprov-jdk18on: 1.85 was ~10.3 MB; 1.86 is ~7.2 MB
• bctls-jdk18on: 1.85 was ~1.5 MB; 1.86 is ~0.85 MB
• bcpkix-jdk18on and bcutil grew slightly

The biggest change is that 1.86 moved or split functionality—especially post-quantum and protocol-related code—into more focused artifacts/providers. The 1.86 release introduces separate areas such as MLS, C509, expanded KEM support, and the separate bctls-klog artifact. The BC provider jar therefore carries fewer classes even though the overall release adds features.
