5.2.0

• Upgrade Groovy to 4.0.14
• Work with Thymeleaf 3.1, using a JavaxServletTestWebExchangeBuilder as the web exchange implementation which is how Thymeleaf 3.0 would have worked. To use a jakarta EE version instead, implement your own JUnitTestExecutor, and include something like:

  private JakartaServletTestWebExchangeBuilder webExchangeBuilder = JakartaServletTestWebExchangeBuilder.create()
  
  @Override
  protected IProcessingContextBuilder getTestProcessingContextBuilder() {
    return new WebProcessingContextBuilder(webExchangeBuilder)
  }
