Replace DomNode#asText with DomNode#asNormalizedTest

[basil]

HtmlUnit 2.55.0 removed the deprecated DomNode#asText in favor of DomNode#asNormalizedTest. Plugins with a very old plugin parent POM (one with HtmlUnit 2.54.0 or earlier) will likely still be using asText and will thus fail to compile until these usages are converted to asNormalizedText.

This and org.openrewrite.jenkins.UpgradeHtmlUnit_3_3_0 could likely be generalized into higher-level OpenRewrite functionality as it is specific to HtmlUnit but not specific to Jenkins.

Looks like this recipe would be a couple of lines of Yaml added to src/main/resources/META-INF/rewrite/htmlunit-3.yml. Would you want to get a first change?

We could indeed create a separate rewrite-htmlunit down the line; right now we only have those yaml recipes I believe, but that could expand once we run against more projects. Let me know if that's something you'd be willing to help maintain, or know folks that would.

For good measure I've also added the HtmlUnit organization repositories to the Moderne platform, if you want to create some goodwill with PRs their way. :)

I see no reason why we should have a separate rewrite-htmlunit. This seems like a better fit for https://github.com/openrewrite/rewrite-testing-frameworks since HtmlUnit is a testing framework.

That could work as well; let me know if you'd like to take that on, or want me to do so.
