Support index-import on all Xcode 16.x versions

Similar to: bazelbuild/rules_swift#1504

Part of #3160

This PR updates the index-import dependency to include both version 5.8 and 6.1 as the hash algorithm changed in Swift 6.1.
To make this change backwards compatible we switch to the 5.8 version on Xcode 16.2 and under.
