Warning for Documentation.docc: found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target

Building a swift package that has swift-algorithms as dependency outputs warning in the terminal

**Swift Algorithms version:** `1.2.0`
**Swift version:**

```
swift-driver version: 1.115 Apple Swift version 6.0 (swiftlang-6.0.0.9.10 clang-1600.0.26.2)
Target: arm64-apple-macosx15.0
```

### Checklist
- [ ] If possible, I've reproduced the issue using the `main` branch of this package
- [x] I've searched for [existing GitHub issues](https://github.com/apple/swift-algorithms/issues)

I see this issue is closed https://github.com/apple/swift-algorithms/pull/237 but I don't see the `exclude` argument in the main branch as suggested in that issue.

### Steps to Reproduce

Build the Hummingbird template project https://github.com/hummingbird-project/template

### Expected behavior
No warning for package documentation

### Actual behavior
```console
warning: 'swift-algorithms': found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target
