isW3C can't be determined for Browserstack responce

[wswebcreation]

Environment (please complete the following information):

• WebdriverIO version: latest
• Mode: Testrunner
• If WDIO Testrunner, running sync/async: both
• Node.js version: -
• NPM version: -
• Browser name and version: Edge
• Platform name and version: Windows
• Additional wdio packages used (if applicable): @wdio/webdriver

Config of WebdriverIO

    capabilities: [{
        'bstack:options': {
            'os': 'Windows',
            'osVersion': '10',
            'local': 'false',
            'seleniumVersion': '3.14.0'           
        },
        'browserName': 'Edge',
        'browserVersion': '18.0',
    }],

Describe the bug
Browserstack is not providing the right capabilities to determine if the instance is a W3C instance. The response contains the following data

const response = {
    'acceptInsecureCerts': false,
    'browserName': 'MicrosoftEdge',
    'browserVersion': '44.17763.1.0',
    'pageLoadStrategy': 'normal',
    'platformName': 'windows',
    'setWindowRect': false,
    'timeouts': { 'implicit': 0, 'pageLoad': 300000, 'script': 30000 },
    'proxy': {},
    'webdriver.remote.sessionid': '993e34c09b8e0d9317347980ab4e186ddc6c06b2'
}

We don't get back a platformVersion and the setWindowRect is false meaning BrowserStack will never be seen as a W3C instance, see also

To Reproduce

Expected behavior
Or BrowserStack needs to fix this, or WebdriverIO needs to come with a patch

Log
see above

The fix for this should be in https://github.com/webdriverio/webdriverio/blob/master/packages/webdriver/src/utils.js#L216 by changing it to:

Object.keys(capabilities).includes('setWindowRect')
