PR lifetime lock

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.

```yaml
name: deploy

on:
issue_comment:
types: [created]
pull_request:
types: [closed]

permissions:
pull-requests: write
contents: write

jobs:
ilock:
runs-on: ubuntu-latest
if: ${{ github.event_name == 'issue_comment' && github.event.issue.pull_request }}
steps:
- name: ilock
uses: github/lock@v2.1.1
with:
lock_trigger: /lock
unlock_trigger: /unlock
lock_info_alias: /wcid
unlock:
runs-on: ubuntu-latest
if: ${{ github.event_name == 'pull_request' && github.event.action == 'closed' }}
steps:

deploy:
