Refactor devcontainer 📦

[sduquemesa]

Context:
Doing some housekeeping here on the devcontainer side.

Description of the Change:

• The previous build script was a bit cumbersome, here it has been simplified.
• Julia installation is now manually managed with juliacall, meaning there is no need for passing the optional JULIA_INSTALL arg to docker build.
• Only a single Dockerfile to create the container. This Dockerfile can also be used to create a completely isolated environment using docker (useful for testing, running simulations, etc.).
• Ensures changes on the code are reflected on the interpreter as they happen. To do so the workspace folder points to /mrmustard where the source code resides.
• Installs the jupyter extension automatically.
• Users can now have the MRMUSTARD_PYTHON_VERSION env-var set in their local environment to dictate which python version the dev container will be built with. When unset, the default value is 3.10. I'd suggest doing this in your bashrc/zshrc/whatever-rc to ensure it's always set and therefore picked up by VS Code

Benefits:

• Click and go 🚀
• Seamless julia installation
• Customizable python version

Possible Drawbacks:
None

haha love it

Were we always using 3.10 for docker, or 3.9?

[sduquemesa]

We had 3.9 to match the lowest python version supported by MrMustard but @ziofil uses 3.10 more often inside devcontainers

[ziofil]

If it were for me I'd use 3.12! Maybe now 3.11 is supported too

[timmysilv]

I have updated the devcontainer definition so it will build with 3.10 by default, but you can specify another version if you please. To do this, just have the MRMUSTARD_PYTHON_VERSION environment variable set locally before building+opening the devcontainer (default will be 3.10).

Some notes:

• I feel like VS Code always refreshes something before building, so I'd put it in your ~/.bashrc, ~/.zshrc` or whatever you use to be safe
• We can't build with 3.12 because tensorflow fails to install 🙃

@ziofil, I've readded oh-my-zsh to the container as default terminal
