Add support for pull_request_review trigger event

[michal-redstone]

Motivation

I noticed that this GH Action, when triggered via pull_request_review event:

• fails to produce summary
• emits this warning:
  

  allcheckspassed/src/checks/checks.ts

  Lines 112 to 118 in 105c017

  	if (!this.ownCheck) {
  	core.warning(
  	`Could not determine own allcheckspassed check (expected name: ${JSON.stringify(
  	ownCheckName
  	)}, this may cause an indefinite loop)`
  	);
  	}

• reports a false-positive result

This is caused by invalid resolution of the PR's HEAD commit SHA, which in turn is needed to fetch check statuses from GitHub API.

Changes

Add pull_request_review to validPullRequestEvents so that the GH Action can resolve the commitSHA properly.

Note that pull_request?.head.sha is defined for pull_request_review event the same as it is for pull_request and pull_request_target events: https://docs.github.com/en/webhooks/webhook-events-and-payloads?actionType=submitted#pull_request_review
