Fix daily action - rename artifacts to just maven repo

[mocenas]

Summary

This PR reverts change on daily.yaml made in #1000

Currently the downloaded artifacts are named maven-repo-, which does not correspond to the one uploaded artifact "maven-repo". It leads to actions failing on non-found artifact. See e.g. https://github.com/quarkus-qe/quarkus-test-framework/actions/runs/7304561952/job/19907115554 which fails on e.g. :
Error: Unable to download artifact(s): Artifact not found for name: maven-repo-windows-build-native

Original reason for making the names unique was to fulfill https://github.com/actions/download-artifact/blob/main/docs/MIGRATION.md . Which states that artifact with one name can only be uploaded once on upload-artifact@v4. But we're uploading the artifact only once on

quarkus-test-framework/.github/workflows/daily.yaml

Line 32 in 2056dcd

- name: Persist Maven Repo

All other occurrences are for downloading the artifact. Therefore there is no need to make the name unique. On the contrary we need the name on downloads to match the name on the upload.

I tried this change here: https://github.com/mocenas/quarkus-test-framework/actions/runs/7384969337/job/20089159569
Pipeline still failed on something, but it fixed the issue with artifact download.
