Skip release candidates when on downloads page (#210)

### Description

For 8.0, we didn't have the release candidates on the release page,
which I think was a miss. This new version now shows each major/minor
pair on the all releases page and in addition also only shows the non-rc
candidate versions on the downloads page.
