ci: `Build (macos-latest, aarch-64-apple-darwin, true)` job fails with "Failed to CreateArtifact" error

[cakebaker]

The following error shows up for the "Build (macos-latest, aarch-64-apple-darwin, true)" job (see, for example, https://github.com/uutils/coreutils/actions/runs/15509483154/job/43668585097?pr=8094#step:16:30):

Error: Failed to CreateArtifact: Received non-retryable error: Failed request: (409) Conflict: an artifact with this name already exists on the workflow run

My guess is that this issue is related to the recent merge of #7964
