The Playwright config snippet emitted `os: 'WIN11'` into the wss://cloud.testingbot.com/playwright
query string. The hub only maps `platform` or `platformName` onto the session platform
(ws-hub src/utils.ts, Utils.generateCapabilities); `os` falls into the catch-all loop that
copies every param into desiredCapabilities, so Capabilities.platform stays undefined and
toDesiredCaps() omits platform entirely. Anyone pasting the snippet got the default OS with
no error rather than Windows 11.

cdp.ts and the selenium/wdio snippets already use platform/platformName — the Playwright one
was the outlier. Regression test asserts the snippet contains `platform: 'WIN11'` and no
`os: 'WIN11'`.
