Remove references to Xcode 16 Beta 1 (just Xcode 16, please.) (#966)

This PR replaces references to Xcode 16 Beta 1, which are generally
centred around our JSON ABI, with references to Xcode 16. All versions
of Xcode 16 use a legacy JSON schema, not just Beta 1.

### Checklist:

- [x] Code and documentation should follow the style of the [Style
Guide](https://github.com/apple/swift-testing/blob/main/Documentation/StyleGuide.md).
- [x] If public symbols are renamed or modified, DocC references should
be updated.
