fix: Ensure Appium Protocol is included when attaching to a session id

[allen-fang]

There is currently a difference in drivers when a session is started through the Appium inspector and when a session is attached.

The commandList are different which is a result of different userPrototypes being set up in webdriver.
https://github.com/webdriverio/webdriverio/blob/e2aa001ecbf240e5240ce551acbfb19f6d004973/packages/webdriver/src/utils.ts#L182

When starting a session, webdriver will determine device type and configure the userPrototypes accordingly. However, when attaching to a session, webdriver doesn't do this which results in the difference in drivers. Since we are attaching to a session in the Appium Inspector, we can assume that the use cases are devices that are mobile so we set isMobile = true in the server options.
