ci: add workflow for duplicating issues to validatorctl

[arturshadnik]

Issue

Description

Adding a workflow to duplicate issues from the plugin repo into validatorctl.

When a new issue is created which requires work in both the plugin and validatorctl repos, it should be labeled with validatorctl. A copy will be automatically made in the validatorctl repo, assigned to the same person, and added to the validator project board.
