fix: revert Chrome to 147.0.7727.57 to match upstream

Chrome 148 introduced more aggressive BFCache activation on Linux headless
CI, causing navigation.goBack ShouldWork to return null (BFCache serves
from cache) and OOPIF tests to be flaky. Upstream Puppeteer still uses
Chrome 147.0.7727.57, so align to that version to avoid these regressions.
