Exported symbols are duplicated in completion list

Does the issue reproduce with Swift 6?

Yes

Description

If I export a symbol from a library to include it in the public symbols of another library then SourceKit-LSP considers these to be separate symbols and will duplicate them in completion lists

Steps to Reproduce

• Create a package with a library called Duplicate using SwiftPM
• Add to source of package @_exported import class Foundation.JSONDecoder
• Create another target that is dependent on the original library target
• Add the following lines

import Foundation
import Duplicate

• Compile
• Now when I type JSON into the file I get two completion entries for JSONDecoder.
