Fix validation errors in plugin documentation (#399)

Fix validation errors in plugin documentation

Depends-On: ansible/ansible-zuul-jobs#1385
SUMMARY

This fixes validation errors in plugin documentation now that ansible
test for 2.13 is running validate-modules on all plugins. The kubectl
connection plugin validation is ignored because there seems to be a
requirement for the author field to have a github username, which we do
not have.
