[MPESW-2436] sshd enabled container

Context

• The container did not expose a way to connect locally through SSH
• It's quite practical to use VS Code (or even an IntelliJ ide) remotely. It will work very well but don't use Copilot since it will make it insanely slow)

What was done

• Added SSHD that listens locally on port 2222 (since 22 is probably already taken).
• The rest of the functionality should remain the same.

TODO

• Maybe allowing to have a different password and customizing the ssh port could be useful for running this container in an external server.

QA

• Tested manually

Review objectives

• knowledge sharing
