Links Broken in ReadME

[pell-je]

many links are broken in the ReadME documentation:

It seems like a lot of info has been moved to the project wiki under the maven repo:
https://github.com/graphql-java-generator/graphql-maven-plugin-project/wiki

For example:
https://graphql-maven-plugin-project.graphql-java-generator.com/client.html

I'm finishing a release for the plugin, and I will update the tutorial.

Thanks for the report
