### Summary
GIT environment variables are not available when connecting to a workspace via SSH
### Steps to reproduce
- Configure Workspaces to work with SSH according to [Connect to a workspace with SSH](https://docs.gitlab.com/ee/user/workspace/configuration.html#connect-to-a-workspace-with-ssh) and try connect to your workspace.
- When connecting via UI, run `env | grep GIT` and observe that git-related environment variables are available:
```plaintext
gitlab-workspaces@workspace-11-1-rkppia-847d69d549-rd64x:/projects/workspace-project$ env | grep GIT
GL_GIT_CREDENTIAL_STORE_FILE_PATH=/.workspace-data/variables/file/gl_git_credential_store.sh
GITLAB_WORKFLOW_INSTANCE_URL=https://GITLAB_URL/
GIT_CONFIG_VALUE_2=admin@example.com
GIT_CONFIG_VALUE_1=Administrator
GIT_CONFIG_VALUE_0=/.workspace-data/variables/file/gl_git_credential_store.sh
GITLAB_WORKFLOW_TOKEN_FILE=/.workspace-data/variables/file/gl_token
GIT_CONFIG_COUNT=3
GIT_CONFIG_KEY_1=user.name
GIT_CONFIG_KEY_0=credential.helper
GIT_CONFIG_KEY_2=user.email
```
- Connect to the same workspace via SSH and run `env | grep GIT` too.
### What is the current *bug* behavior?
GIT variables are not set:
```plaintext:
gitlab-workspaces@workspace-11-1-rkppia-847d69d549-rd64x:/projects/workspace-project$ env | grep GIT
gitlab-workspaces@workspace-11-1-rkppia-847d69d549-rd64x:/projects/workspace-project$
```
### What is the expected *correct* behavior?
According to the internal discussion with @vtak, it is not expected, and variables should be set.
### Additional information
The image I've specified in the `.devfile.yaml` uses this Dockerfile:
```plaintext
FROM ubuntu:20.04
# Install `openssh-server` and other dependencies
# Note, need to install recent git releases when using ubuntu 20.04 image
ARG DEBIAN_FRONTEND=noninteractive

WORKDIR $HOME
RUN mkdir -p /home/gitlab-workspaces && chgrp -R 0 /home && chmod -R g=u /etc/passwd /etc/group /home
# Allow sign-in access to `/etc/shadow`
RUN chmod 775 /etc/shadow
RUN wget -O /usr/local/bin/kubectl https://dl.k8s.io/release/v1.29.4/bin/linux/amd64/kubectl && chmod 755 /usr/local/bin/kubectl
RUN locale-gen en_US.UTF-8
USER gitlab-workspaces
```
- It is not possible to make a commit because username and email are not set. After setting `git config --global user.email` and `git config --global user.name`, I was able to make a commit to the repo.
