Fix tests and Linux support
## Changes - Fix unit tests. - Remove unnecessary Combine imports - Fix imports on Linux. - Fix unit tests on Linux + Add missing compile checks for `XCTExpectFailure` in Linux + Disable tests that use `@MainActor` on Linux because of an issue gathering tests: https://github.com/apple/swift-corelibs-xctest/issues/424 - Remove Swift installation from SwiftPM Linux job, as Swift is already included in `ubuntu-latest` (`ubuntu-20.04`): https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2004-Readme.md#language-and-runtime
