Update entrypoints after argo pr 12707

[gczuczy]

Is your feature request related to a problem?

The entrypoint change in argoproj/argo-cd#12707 is another step for making a distroless image possible.
Currently the argocd helm chart does not make it possible to remove the entrypoint.sh from the manifests for using tini directly instead.

Once the PR is merged, entrypoint.sh can be removed from the manifests, and all services started directly with args. Please see the first comment in the PR for details and kubernetes docs on the topic.

Describe the solution you'd like

Removing the dependency on any kind of shell, so there's one less blocker for a distroless image.

Describe alternatives you've considered

I'm not sure there are a lot of alternatives, tini is pretty much accepted as the de-facto standard for container entrypoints.
