ci - `Upload Artifacts` step fails with error `Error: Failed to CreateArtifact: Failed to make request after 5 attempts`

### What is this about?
There's an intermittent failure on the `Upload Artifacts` step which logs this error: `Error: Failed to CreateArtifact: Failed to make request after 5 attempts: Request timeout: /twirp/github.actions.results.api.v1.ArtifactService/CreateArtifact`

It's unclear if the `Run e2e tests` previous step run successfully or not, because it's not clickable in the link. So it could also be that there's a problem in the previous step, causing then an error to the next one (unsure, but something to look).

Start with the two linked GitHub Actions job logs and inspect the `Run e2e tests` and `Upload Artifacts` steps, including whether the earlier step completed successfully. Determine the cause of the intermittent CreateArtifact timeout and verify that artifact uploads complete reliably without obscuring the preceding step's status.
