### Description of the change

In the previous PR I changed the minor version of the GH CLI correctly,
but failed to change the patch version, resulting in a release that does
not exist:


https://github.com/vmware-tanzu/kubeapps/pull/6209/files#diff-5b6cd7ed775959abb6c5484c9dabb475d5bb5c55850de016832356722ec3f7f8R40-R41

### Benefits

Full-integration pipeline can download the GH CLI.
