Undeclared SwiftSyntaxMacroExpansion dependency on SwiftOperators

Description

When building with --explicit-target-dependency-import-check error, swift-syntax fails to build due to the error: error: Target SwiftSyntaxMacroExpansion imports another target (SwiftOperators) in the package without declaring it a dependency..

Steps to Reproduce
