Add API Support to Download Artifacts from Actions

[MrDiba]

Feature Description

As far as I know, currently, the Gitea API does not provide a direct method to download artifacts generated by Gitea Actions (using actions/upload-artifact). This feature request proposes adding an endpoint that enables users to download workflow artifacts via the API.

In the webbrowser the /repos/{owner}/{repo}/actions/runs/{run_id}/artifacts endpoint is available and I'm able to download the artifact using curl by first getting an cookie and then by using the cookie to get the artifact. But I think it would be better to directly use the API with token authentication.
