I'll fix the CI fails soon

I think dirname and basename are not a good case for making people use \Magento\Framework\Filesystem\Io\File::getPathInfo. The given better uses rely on an implementation detail (the returned array happens to conform to the pathinfo output) with the array having dirname and basename as keys. But this is not really part of any @api guarantees.

I believe it would be better to fix the framework first, either by adding extra methods ie getDirname and getBasename or by adding an optional input to pathinfo($filePath, $args = null) and then advise people to use those stable implementations.

I agree with @fooman here. Neither \Magento\Framework\Filesystem\Io\File nor \Magento\Framework\HTTP\Adapter\Curl are marked with @api, so I'd avoid such recommendation for now.

Have to close this PR since we cannot recommend using non-api classes.
