Fixes broken link in docs.

Fixes #24428

I think when 1.12.0 is formally released, we want to have the link pointing to 1.12.0 not 1.12.0-rc3. So there might be a chicken and egg issue here. We probably need to change back to 1.12.0 just before the 1.12.0 release (or cherry pick the change).

yes, its horrible that we've released broken documentation for a release that hasn't happened yet :(

unfortunately, the docs tooling expects there should be no broken links - and we've finally fixed enough that these are standing out like sore thumbs.

The other option, is to defuse the links (ie, put backtics around them)

@joaofnfernandes @thaJeztah what if we set the links to https://github.com/docker/docker/releases/ for now, and someone promises to fix it when 1.12.0 actually happens?

[joaofnfernandes]

I've changed the link to point to https://github.com/docker/docker/releases/.

In my opinion if we decide to link to something, we need to ensure that page exists, otherwise we're providing a bad user experience.
The other option is not linking, which also works.

Alright, let's go for this, given that we remove it before GA
