[chore] upgrade actions/upload-artifact and actions/download-artifact to v4 (open-telemetry#31236)

The upgrade of `actions/upload-artifact` and `actions/download-artifact`
is a breaking change.

1. Both actions need to be upgraded together, as downloading artifacts
uploaded with previous version does not work.
2. A breaking change in `upload-artifact` is that you cannot upload to
the same artifact name twice.

The second point lead to the changes in this pull request. I have
modified the names of artifacts to hopefully prevent conflicts.

**Link to tracking Issue:**

open-telemetry#30102

**Testing:**

The changes to the `build-and-test` and `e2e-test` workflows are tested
in this PR's checks. The changes to the `load-test` workflow can only be
tested after merging to main, I'm afraid, as this is when this workflow
is triggered.
