Show the corresponding element when noheader is true

[mcruzdev]

          I have a doubt, I am working on this [pull request](https://github.com/quarkiverse/quarkus-qute-web/pull/102) to make a PoC with this tooling (thank you for this great job)!

I have a test here:

    @Test
    public void testH1() {
        Engine engine = Engine.builder().addDefaults()
                .addSectionHelper(new AsciidocSectionHelperFactory()).build();

        String result = engine.parse("{#ascii}= Quarkus and Roq{/ascii}").render();

        assertThat(result).contains("<h1>Quarkus and Roq</h1>");
    }

The result is "" but the expected is to have <h1>..., It happens when I add noheader attribute, is it the expected behavior?

I think it should be <h1>... no?

Seems it is right for asciidoctor (https://github.com/asciidoctor/asciidoctor/blob/main/lib/asciidoctor/converter/html5.rb#L193) but we also consider noheader there (https://github.com/yupiik/tools-maven-plugin/blob/master/asciidoc-java/src/main/java/io/yupiik/asciidoc/renderer/html/AsciidoctorLikeHtmlRenderer.java#L299). We should probably add to the configuration a backward compatible toggle to keep current behavior since the reasoning was that when embed the title (=) was managed by the embedder and not the renderer.

One way is to consider the notitle value instead of just testing the presence maybe? if false we use it whatever noheader is?
