What happened?

When setting overwrite: true, upload sometimes fails with the following output:

Run actions/upload-artifact@v4
  with:
    name: pull-request-number
    path: pull_request_number.txt
    overwrite: true
    if-no-files-found: warn
    compression-level: 6
  env:
    FORCE_COLOR: 1
    FLAKINESS_CONNECTION_STRING: 
    ELECTRON_SKIP_BINARY_DOWNLOAD: 1
    PWTEST_BOT_NAME: ubuntu-latest-node18-1
With the provided path, there will be 1 file uploaded
Artifact name is valid!
Root directory input is valid!
Error: Failed to CreateArtifact: Received non-retryable error: Failed request: (409) Conflict: an artifact with this name already exists on the workflow run

What did you expect to happen?

One of the job succeeded and other silently continue doing nothing as documentation of the option suggests.

How can we reproduce it?

Configure several parallel jobs within a workflow and matrixes to write into the same artifact with overwrite: true, something like this:

    - name: Upload artifact with the pull request number
      if: always() && github.event_name == 'pull_request'
      uses: actions/upload-artifact@v4
      with:
        name: pull-request-number
        path: pull_request_number.txt
        overwrite: true

The upload action will fail sometimes, e.g. see this run.
