fix: use appium:platformVersion in browserName (if present)

Use the value of `appium:platformVersion` (if present) in `browserName`.

Since the [capabilities config when using Appium][1] does not include a
browser version, but only the platform version, including the value of
`appium:platformVersion` in `browserName` is essential in order to be
able to identify which platform the logs refer to.
