chore(ci): Remove Package@swift-5.9.swift

[itaybre]

📜 Description

Removes Package@swift-5.9.swift since it is not needed anymore.

💡 Motivation and Context

Package@swift-5.9.swift was added because we needed some configuration specific to visionOS.
Since that is not needed anymore (after #6077), we can remove it.

💚 How did you test it?

📝 Checklist

You have to check all boxes before merging:

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

No user changes, so #skip-changelog

High-risk code can easily blow up and is hard to test. We had severe bugs in the past. Be extra careful when changing these files, and have an extra careful look at these:
