Deploy To AppStore Connect - Specify metadata directory path

Description of the feature request

When uploading to AppStore connect, we have different Delivery files for the different flavors (Targets) of our project.

We would need a way to specifiying the metadata path, to let the workflow upload them for us.

Use case / for what or how I would use it

Within the skip metadata option (yes or no) append an optional value to specify the path of the metadata directory.
