fix: don't display pending reviews as participants (#10528)

Fixes #10155

When participants are displayed, don't include those that only have made a pending review. Those should not yet be revealed as participants.

Apart from adding automated tests, this is the manual verification process I've followed:
1. Set up three users
2. User 1 creates a repository, then creates a pull request adding a new file
3. User 2 creates a new code comment but doesn't not publish the review, shows as pending.
4. User 3 creates a new code comment and publishes the review.
5. From everyone's perspective the number of participants is: 2. And, the participants displayed in the list are 1 and 3. User 2, which hasn't yet published the review is not displayed.
