Reorder release notes labels (#2599)

Problem: Many of our test changes also include markdown file changes, and the docs label is prioritized in our release notes over tests. This means that the docs sections of the notes often contained many tests changes.

Solution: Prioritize the test label first over docs to hopefully better organize release notes.
