feat: Add workflow to cancel specific workflows

This commit introduces a new workflow that allows for the cancellation of other workflows.

- It accepts workflow ID(s) as input, allowing for the cancellation of multiple workflows.
- It provides options to cancel runs based on their state: queued, in_progress, or all.
- A cancellation reason can be provided as input.
- It leverages the `actions/github-script` action to interact with the GitHub API and cancel the specified workflow runs.
