[spaceship] add visionOS support for Connect API

[triplef]

Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I see several green ci/circleci builds in the "All checks have passed" section of my PR (connect CircleCI to GitHub if not)
• I've read the Contribution Guidelines
• I've updated the documentation if necessary.
• I've added or updated relevant unit tests.

Motivation and Context

This is a simple rebase of #21929 onto master because the original author has not been able to do so in the past month and it would be great to have this in Fastlane to (I think?) complete visionOS support.

The only difference to the original commit is that the changes in spaceship/connect_api.rb were discarded as master already contained the same addition of visionOS.

Description

See #21929.

All credit goes to @yanniks for implementing the changes.

Testing Steps

I have used it to upload our visionOS app to App Store Connect using deliver.
