indexOf() replaceable by contains()

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

Checking if a value is included in a String or List using indexOf(value)>-1 or indexOf(value)>=0 can be replaced with contains(value). Using contains() expresses the intent more directly and avoids the mental overhead of interpreting index comparisons.
