### Summary by OpenAI

New Feature: This pull request adds a new `pull_request_review_comment`
event type and modifies the `concurrency` section to cancel in-progress
jobs. It also adds a new input parameter `review_comment_lgtm` to the
`jobs` section. These changes provide more flexibility for users when
setting up their workflows.
