Add tasks for moving issues to other repos

Editor assessment

The subject states the automation addition plainly: tasks were added for moving issues between repositories, which names both the mechanism and its purpose. chore(bot) pairs the correct type with the automation scope, which is genuinely informative context. No body or footer, and none is required for a task registration whose subject is self-sufficient; the pull number gives provenance. Wording is imperative and compact. Proportionate and complete for an infrastructural housekeeping change.
