Subject: [PATCH] Use the native `concurrency` property to cancel workflows
 (#4572)

I noticed that some of our workflows aren't getting cancelled when a new one has been triggered, so we ended up having a long queue in our CI when multiple changes are triggered in a short period.

Looking at the comment here, I noticed the list of workflow IDs are outdated and no longer exist, and some new ones are missing:
https://github.com/sigp/lighthouse/blob/dfcb3363c757671eb19d5f8e519b4b94ac74677a/.github/workflows/cancel-previous-runs.yml#L12-L13

I attempted to update these, and came across this comment on the [`cancel-workflow-action`](https://github.com/styfle/cancel-workflow-action) repo:
> You probably don't need to install this custom action.
>
> Instead, use the native [concurrency](https://github.blog/changelog/2021-04-19-github-actions-limit-workflow-run-or-job-concurrency/) property to cancel workflows, for example:

So I thought instead of updating the workflow and maintaining the workflow IDs, perhaps we can try experimenting the [native `concurrency` property](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#concurrency).
