ci: Fix the WPT export job after the repository change (#33228)

The GitHub search API is a bit sensitive. There isn't a great way to
search for the repository organization and the branch name when looking
for open PRs. Instead use the bot username as the author name, which
should likely have been having before. This fixes the WPT export job.
