[docs] update path to iTMSTransporter for Fastlane.swift

[rafauke]

The path provided in the document no longer works, iTMSTransporter has to be run from a different directory.

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.

This is not ideal fix IMO. From Xcode 14, there is no iTMSTransporter and officialy removed. So it would be better to consider the path which is expected to use Transporter.app

Correct. This is just to help people that are looking for the transporter right now. Maybe both messages should be present for historical/backwards compatibility reasons.
