[Bug]: No run env vars in non-login SSH session

[un-def]

Steps to reproduce

Apply the configuration:

# dev-environment.dstack.yml
type: dev-environment
name: dev-environment
ide: vscode
env:
  - RUN_VAR=1

1. Log in and run command:

   $ ssh dev-environment
   root@a6e6bda7be8e:/# printenv SHELL CUDA_VERSION DSTACK_RUN_NAME RUN_VAR
   

2. Run the same command via ssh:

   $ ssh dev-environment printenv SHELL CUDA_VERSION DSTACK_RUN_NAME RUN_VAR
   

Variable sources:

• SHELL — set by sshd
• CUDA_VERSION — from the image
• DSTACK_RUN_NAME — injected by dstack
• RUN_VAR — declared in the run configuration

Actual behaviour

1. /bin/bash
   12.8.1
   dev-environment
   1
   

2. /bin/bash
   

Expected behaviour

The output in the second case should be the same.

Additional information

dstack exports vars in /dstack/profile, which is sourced in /etc/profile, which, in turn, only sourced by login shells, while ssh destination command [argument ...] executes command in a non-login shell.
