Fix accidentally malformed yaml in GitHub action (#2085)

Summary: Fix accidentally malformed yaml in GitHub action

This was a minor mistake from #2079.

Relevant Issues: N/A

Type of change: /kind bugfix

Test Plan: GitHub actions on PR builds should pass once this is merged
(since `pull_request_target` uses the copy off main)
- Also visually inspected the #2079 change again to verify nothing else
was missed.
