Upgrade inadequate cryptographic key sizes

Recipe IDorg.openrewrite.java.security.UpgradeInadequateKeySizeArtifactorg.openrewrite.recipe:rewrite-java-security

Rewrites cryptographic key-size literals that fall below current minimums. RSA/DSA/DH < 2048 bits are upgraded to 2048; EC < 224 bits are upgraded to 256 (when the algorithm is resolvable from KeyPairGenerator.getInstance(...)); symmetric (AES) < 128 bits to 128; weak named EC curves (e.g. secp112r1, prime192v1) to secp256r1. Companion fix recipe to FindInadequateKeySize. Note: changing key sizes can break interop with existing artifacts; review before applying.
