Description

In recent 6.4 toolchains, we're seeing this warning when building a package where a target contains a .docc bundle:

warning: 'swift-testing': found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target
    /Users/runner/actions-runner/_work/swift-testing/swift-testing/Sources/Testing/Testing.docc

This warning was not produced in 6.3 or earlier and appears to be a regression.
