Correct download badge URL in nightly release workflow

The download count badge in the `nightly-release.yml` workflow was pointing to a generic `/nightly/total` URL. This has been corrected to use a version-specific URL, `nightly-${{ env.version }}/total`, ensuring the badge accurately reflects downloads for each individual nightly release.
