How to correctly manage Release Candidates releases

[ranshid]

Currently after 8.1.0-rc1 release we have the following presented on the webpage:

1. On the download page we have the latest GA release reported as the latest release (I think we should place some indication like "Latest stable release") and no RCs are reported there
2. On the release page we have the release candidate presented, but only in case there is not yet any "stable"/GA release. So for 8.1.0-rc1 is currently shows there.
3. the url for the release download is currently made up of --. So, for example, 8.1.0-rc1 has the url: https://valkey.io/download/releases/v8-1-0/ which does NOT include the 'rcN' tag. Thios has the advantage that users can continue using the link and have it "automatically" updated when we issue a new RC, but users also lose the ability to download old RCs.

This raises the following quesitons:

1. should we explicitly indicate Release candidate on RCs release download pages? (currently the only indication is that the download ref name is 8.1.0-rc1 )
2. should we keep a single url link for each release (like today)? I thin it might make sense to have a dedicated link for each RC but it means we will have to persist them in our web repo and not just "remove" them after a new RC is released.

I would suggest the following:

1. We should manage and persist RC releases download url links.
2. We should keep RC links on the release page. users should be able to download the specific RC later in orer to compare changes and reproduce bug fixes IMO.
3. We should explicitly state on the download page that this is the latest STABLE release.

I think your suggestions are all reasonable.
