Find use of insecure random number generation in Go

Recipe IDorg.openrewrite.golang.security.search.FindInsecureRandomArtifactorg.openrewrite.recipe:rewrite-java-security

Finds Go calls into math/rand and math/rand/v2. These generators are not cryptographically secure and must not be used to produce secrets, tokens, nonces, salts, or any other security-sensitive value. Use crypto/rand instead.
