Changelog generator: thank PR reviewers instead of phpstan-bot

When a PR was created by @phpstan-bot, the changelog would previously
thank the bot. Instead, fetch the PR's reviews via the GitHub API and
thank the people who actually reviewed the PR, excluding the maintainer
and the bot itself. Supports thanking multiple reviewers.
