Replace A.class.isInstance(a) with a instanceof A

Recipe IDorg.openrewrite.staticanalysis.ReplaceClassIsInstanceWithInstanceof
Artifactorg.openrewrite.recipe:rewrite-static-analysis

There should be no A.class.isInstance(a), it should be replaced by a instanceof A. Using instanceof enables the compiler to catch type incompatibilities at compile time rather than silently passing at runtime, which helps detect dead code early.
