Can't synchronize ArgoCD App

[pbrissaud]

Describe the bug
I'm trying to install Loki using ArgoCD, but I encounter the following error during the installation process:

Failed to load target state: failed to generate manifest for source 1 of 2: rpc error: code = Unknown desc = failed to initialize repository resources: rpc error: code = Internal desc = Failed to checkout FETCH_HEAD: `git submodule update --init --recursive` failed exit status 128: fatal: No url found for submodule path '_shared-workflows-dockerhub-login' in .gitmodules

This error is similar to the issues discussed in #14896 and #14966, which were fixed last week by PR #14883. It appears to be caused by an extra file referencing a git submodule. However, this problem has been reintroduced in commit 5897e08, which was made after the fix in PR #14883.

To Reproduce
Steps to reproduce the behavior:

1. Set up ArgoCD to deploy Loki.
2. Attempt to sync the Loki deployment.
3. Encounter the error during the sync process.

Expected behavior
Loki should be successfully deployed via ArgoCD without any submodule issues.

Environment:

• Infrastructure: Kubernetes GKE
• Deployment tool: ArgoCD - Helm + values files

Completely agree with you @pbrissaud. I have the same problem again.

@trevorwhitney could you check it again, please?
