chore(browserstack): Update browserstacktunnel-wrapper, fix options

Only the latest version of the package works correctly (the backend for it at
BrowserStack is not versioned) and the options have changed in the new version
of the package.

Also, iOS 8.0 is no longer available on BrowserStack, only 8.3 is. Instead,
this commit changes it to 9.3 as we shouldn't be testing on 8 anymore anyway.

(a late cherry-pick of ad0bb83)

Closes #15892
