Simplify AssertJ assertions on == and != comparisons

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

Replace assertThat(x == y).isTrue() and its variants with the dedicated assertion for whatever == actually compares: assertThat(x).isNull() against the null literal, assertThat(x).isEqualTo(y) when either operand is a primitive and the comparison is therefore by value, and assertThat(x).isSameAs(y) when both operands are reference types. Floating point operands are left alone, as == and isEqualTo disagree on NaN and -0.0.
