gradle 7.2 compatibility

[epiatakov]

Hi, I have an error with 7.2 gradle:

A problem was found with the configuration of task ':deployBevis' (type 'DeployWildflyTask').

• In plugin 'com.mkring.wildlydeplyplugin.deploy-wildfly-plugin' type 'com.mkring.wildlydeplyplugin.DeployWildflyTask' property 'log' is missing an input or output annotation.

  Reason: A property without annotation isn't considered during up-to-date checking.

Possible solutions:

1. Add an input or output annotation.
   2. Mark it as @internal.

Please refer to https://docs.gradle.org/7.2/userguide/validation_problems.html#missing_annotation for more details about this problem.

I guess with new gradle versions the @internal annotation should be used there. You probably could also downgrade gradle instead.

I didn't work with wildfly since a couple of years, but will happily review and merge contributions :)
