Fix build failure on Linux

[finestructure]

This fixes the build error reported in #302 , although I'm not sure this is the right fix.

• Tests on macOS/Swift 6 pass
• Tests fail to compile on Linux/Swift 6 but it is not a regression. It also fails on Linux/Swift 6 for 1.4.1:

/host/Tests/DependenciesTests/DependencyValuesTests.swift:462:13: error: sending main actor-isolated value of type 'DependencyValuesTests' with later accesses to nonisolated context risks causing data races
 460 | 
 461 |       model.doSomething(expectation: expectation)
 462 |       await fulfillment(of: [expectation], timeout: 1)
     |             `- error: sending main actor-isolated value of type 'DependencyValuesTests' with later accesses to nonisolated context risks causing data races
 463 |     }

Tests compile if I comment out this test testEscapingInFeatureModel_InstanceVariablePropagated.

Tests then mostly pass but there's a crash in the end. I'm not sure if it's due to "Swift Testing" and some cleanup or if it's a test that's crashing:

Hope this helps, just wanted to leave some info!

We'll pin to 1.4.1 for now, although I'm a bit worried that our platform Linux/Swift 6 isn't passing tests for 1.4.1, either 😬

Thanks! Made a small edit from where previewValues is defined.
