Fix and simplify spreadsheet action

- Remove `pull-request-review` event. When triggered
  by this event, secrets are not available. This fixes
  the action failure when pull request reviewed.
- Remove unnecessary nuanced event settings. Generally
  the spreadsheet date should get updated on all associated
  events.
