[ENH] - Make code server a login shell to act the same as jupyterlab

[Adam-D-Lewis]

Feature description

Currently, vs code terminal will not source .bash_profile if it exists, but jupyterlab does. The behavior can be standardized in Nebari by adding

{
    "terminal.integrated.defaultProfile.linux": "bash",
    "terminal.integrated.profiles.linux": {
    "bash": {
        "path": "bash",
        "args": ["-l"]
    }
    }
}

to the ~/.local/share/code-server/Machine/settings.json file on a Nebari deployment. Perhaps we could add this file, but still make it editable by the users.

Value and/or benefit

Make a consistent experience between Code server and jupyterlab.

Anything else?

I back this 1000%. Its confusing to users if you don't realize this.
