• The roll workflow has a new branch input, default main. It names the branch to roll in both repositories: release-1.65 rolls the release-1.65 branch of playwright-python to the tip of release-1.65 of microsoft/playwright.
• The bot starts from that branch, so the old pin is the DRIVER_VERSION of the branch, and it opens the PR to that branch.
• The ref input is now empty by default, which means the tip of branch. It still rolls to another upstream branch, tag or commit.
• The scheduled roll is a roll of main. It skips only while a roll PR to main is open.
