As of #18986, we're creating links to the docs using the helper util/docs.ts to make sure they point to the version of the docs for the version of the cluster. However, the version number is hardcoded there. There's already a TODO item there, but since this is something we definitely don't want to get lost, I'm also making an issue to keep track of it.

We should figure out a way to DRY this so it's not hardcoded (we can get it from pkg/base/docs). Until then, for every release we'll need to update the version string in the client.
