Expose assets filepath URL on UI

What does this MR do?

Provide the frontend component of the asset link redirection. Visually nothing will change, but the link will actually the direct_asset_url rather than url, and will redirect in the backend.

On the release/releases page, instead of linking the linux amd64 file of v11.9.0-rc2 release as https://gitlab-runner-downloads.s3.amazonaws.com/v11.9.0-rc2/binaries/gitlab-runner-linux-amd64 (the target URL where the file is stored) it should be linked as https://gitlab.com/gitlab-org/gitlab-runner/releases/v11.9.0-rc2/binaries/gitlab-runner-linux-amd64. Notice that the filepath is added to the release direct page.
