Remove redundant dependencies

[Celebrate-future]

@chenjianjx Hi, I am a user of project com.github.chenjianjx:wsdl2html:4.2.1. I found that its pom file introduced 39 dependencies. However, among them, 22 libraries (56%) have not been used by your project (the redundant dependencies are listed below). Reduce these useless dependencies can help prevent conflicts between library versions. MeanWhile, it can minimize the total added size to projects. It can also help enable advanced scenarios for users of your package.
This PR helps com.github.chenjianjx:wsdl2html:4.2.1 lose weight :) I have tested the revised configuration in my local environment. It is safe to remove the unused libraries.

Best regards

Hi,

• with what tool did you find they are useless?
• did you test it in both jdk 8 and jdk 11? JDK 11 changed a lot when it comes to xml
