UpgradeDependencyVersion with overrideManagedVersion does not add property if <relativePath> is missing

[Goshenkata]

Adding this test case in UpgradeDependencyVersionTests fails - the recipe makes no changes

    @Test
    void upgradeVersionDefinedViaImplicitPropertyInRemoteParentOfLocalParent_withoutRelativePath() {
        rewriteRun(
          spec -> spec.recipe(new UpgradeDependencyVersion("org.flywaydb", "flyway-core", "10.15.0", "", true, null)),

The root cause is AddProperty where the is this check

// If there is a parent pom in the same project, update the property there instead
                if (document.getRoot().getChild("parent")
                        .flatMap(tag -> tag.getChild("relativePath"))
                        .flatMap(Xml.Tag::getValue)
                        .flatMap(v -> v.trim().isEmpty() ? Optional.empty() : Optional.of(v))
                        .isPresent()

However relativePath can be ommited and then it's implicitly "../pom.xml" a more proper check could be:

if (getResolutionResult().parentPomIsProjectPom())

But this breaks some callers of the AddProperty.
