Fix mismatch between hook events and github event types (#24048) (#24091)

Backport https://github.com/go-gitea/gitea/pull/24048

Some workflow trigger events can have multiple activity types, such as
`issues` and `pull_request`, and user can specify which types can
trigger the workflow. See GitHub documentation:
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows

Now some hook events cannot match the workflow trigger events correctly
because we don't check the activity types. For example,
`pull_request_label` is an individual hook event. But there isn't a
`pull_request_label` workflow trigger event, we can only use
`pull_request` event's `label` activity type. If we don't check the
activity types, the workflows without the `label` activity type may be
triggered by the `pull_request_label` event by mistake. We need to
improve the match logic.
