userAgentData doesn't function as expected if the web page isn't in a secure context. #198

In the event that the page is controlled by the DevTools protocol (webdriver), userAgentData exists but lacks information. For example, when running Playwright after a clean installation using npx playwright test, you may encounter the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'brand')
    at collector (rum:1:16120)
    at rum:1:20575
    at sentryWrapped (helpers.ts:77:19)

As for the behavior of the navigator.userAgentData API, it returns:

{
    "brands": [],
    "mobile": false,
    "platform": ""
}

Canarytrace RUM now logs attributes.browser: "automated" if the web page is controlled by an automation framework.
