Use better font family for integrated terminal

[christian-bromann]

Current Behavior

Given my VS Code Runme configurations:

"runme.experiments.grpcRunner": true
"runme.terminal.interactive": true
"runme.terminal.nonInteractive": true

If I run a code cell in interactive or non-interactive mode the terminal font is not a monospace one:

Desired Behavior

I am not sure the origin of this problem. If I set-up VS Code incorrectly, I would like to see better docs on how this can be configured better. If my configuration is not at fault I would love to see Runme using a better default font family.

Discussed this, turns out VSCode has a fallback mechanism when the font isn't installed on the system, which the notebook terminal does not have.

One solution is to use the FontFaceSet API

Bromann pointed out if this isn't fixed it should be noted as part of stateful/runme.dev#119

I'm unable to reproduce this as of today. However, if it's still an issue, let's reopen.
