PR lifetime lock

[imranismail]

I can't get this to work with headless mode and PR lifetime lock. The unlock would trigger for any PR that was closed and because the lock was locked using headless mode, there is nothing that ties the lock to the pull-request.

name: deploy

:wave: @imranismail, happy to help!

Firstly, it should be noted that this Action is considered supplemental to the main github/branch-deploy Action. This Action is mainly used when more advanced or custom "lock" operations are required that the branch-deploy Action cannot handle out-of-the-box. If you are using this Action in conjunction with deployments, I would highly suggest using the github/branch-deploy Action to obtain locks on pull requests as it will add metadata to the lock file that can be used to associate a lock with a pull request. See below:

Example commenting .lock <environment> on a pull request using the github/branch-deploy Action:

When performing a "lock" operation on a pull request using the github/branch-deploy Action, a link to the issue comment is left as metadata within the lock file. The link can be used to reference the pull request. Here is a live example:

{
    "reason": null,
    "branch": "test",
    "created_at": "2023-10-25T17:25:28.893Z",
    "created_by": "GrantBirki",
    "sticky": true,
    "environment": "production",
    "global": false,
    "unlock_command": ".unlock production",
    "link": "https://github.com/GrantBirki/actions-sandbox/pull/93#issuecomment-1779733746"
}

If the above comment does not complete what you are after, changes will likely need to be made to this Action to add more metadata into the lock.json file that will allow some sort of reference or ties back to a pull request.

Would you be happy to accept a PR for this?

I don't mind contributing to it, as I had a deep look into the code and found that the metadata was the key to enable this.
