helm plugin update would not work(workaround exists)

### Current Behavior ``` helm plugin update secrets level=WARN msg="cannot get information about plugin source" location=/home/ok/.local/share/helm/plugins/secrets error="Cannot detect VCS" Error: failed to update plugin secrets, got error (cannot get information about plugin source) ``` ### Expected Behavior And this is expected cause installation for now works only with direct link to archive. #639 ### Steps To Reproduce ```markdown Install with: helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.0/helm-secrets-post-renderer.tgz --verify=false helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.0/helm-secrets-getter.tgz --verify=false helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.0/helm-secrets.tgz --verify=false than try to update with `helm update` ``` ### Environment - Helm Version: 4 - Helm Secrets Version: 4.7.0 to 4.7.1 - OS: Fedora 43 - Shell: bash ### Anything else? Actually workaround(I could guess) is to remove than install: ``` helm plugin remove secrets-getter helm plugin remove secrets helm plugin remove secrets-post-renderer ``` than ``` helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.1/secrets-post-renderer-4.7.1.tgz --verify=false helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.1/secrets-getter-4.7.1.tgz --verify=false helm plugin install https://github.com/jkroepke/helm-secrets/releases/download/v4.7.1/secrets-4.7.1.tgz --verify=false ```
