fix artifact range requests (#4218)

Browse Source 
I noticed that Forgejo does not allow HTTP range requests when downloading artifacts. All other file downloads like releases and packages support them.

So I looked at the code and found that the artifact download endpoint uses a simple io.Copy to serve the file contents instead of using the established `ServeContentByReadSeeker` function which does take range requests into account.
