Describe the bug

When my code has private git submodules, the build step fails. The error is as follows -

# Unable to update submodules: Error: Command failed: git submodule update
                                    Cloning into '/codebuild/output/src3058105818/src/<repo>/src/components/common-css-components'...

Expected behavior

It should be able to clone the sub module with the connect git app has been provided access to the git sub module repository

Reproduction steps

1. Add a private git repo to your amplify app
