cluster-api: `clusterctl version` shows wrong version for the v1.0.0 release

What steps did you take and what happened: Download the clusterctl binary from the v1.0.0 release artifacts: https://github.com/kubernetes-sigs/cluster-api/releases/download/v1.0.0/clusterctl-linux-amd64

Run clusterctl version.

The clusterctl binaries of the v1.0.0 release report the wrong version.

What did you expect to happen: clusterctl version should report the version as v1.0.0. Got:

clusterctl version: &version.Info{Major:"1", Minor:"0", GitVersion:"v1.0.0-rc.0.42-e09ed61cc9ba8b", GitCommit:"e09ed61cc9ba8bd37b0760291c833b4da744a985", GitTreeState:"clean", BuildDate:"2021-10-06T16:11:06Z", GoVersion:"go1.16.8", Compiler:"gc", Platform:"linux/amd64"}

New clusterctl version available: v1.0.0-rc.0.42-e09ed61cc9ba8b -> v1.0.0
https://github.com/kubernetes-sigs/cluster-api/releases/tag/v1.0.0

clusterctl shows a git version that is not v1.0.0 and suggests that an update is available.

It should show the version as v1.0.0.

The same happens for the darwin binary as well.
