Is your feature request related to a problem? Please describe.
Just like many other plugins, a skip parameter is welcomed to be there. When set as true, the current execution shall be ignored as it is.
The use case is, I created a parent pom which has all the configurations and executions in it. By doing so, I do not have to do repeatted configuration thing anymore, given there is not much configurational change from project to project.
But when comes tographql-java-codegen-maven-plugin, when I do the same, because there is no skip parameter, it always generate whatever I configured in parent.

Describe the solution you'd like
One skip boolean parameter, to skip the current execution when set as true

Describe alternatives you've considered
We may name the skip the other way, but the feature itself has no alternative.
