Simplify literal-first AssertJ size assertions to hasSize

Recipe IDorg.openrewrite.java.testing.assertj.SimplifyHasSizeFromIsEqualToAssertion
Artifactorg.openrewrite.recipe:rewrite-testing-frameworks

Replace assertThat(<int literal>).isEqualTo(collection.size()) style assertions with the dedicated assertThat(collection).hasSize(<int literal>). Only the structural size form is rewritten, where the comparison is on a primitive int and reversing the assertion is behavior-preserving (unlike arbitrary isEqualTo object comparisons, which rely on equals).
