Build container doesn't install rustfmt

[hulto]

Describe the bug
The automatic code formatting that the dev container does requires rustfmt
This results in an error every time a rust file is saved.

[Error - 12:36:26 AM] Request textDocument/formatting failed.
  Message: rustfmt exited with:
                           Status: exit status: 1
                           stdout: 
                           stderr: error: 'rustfmt' is not installed for the toolchain 'nightly-2023-09-04-x86_64-unknown-linux-gnu'
To install, run `rustup component add rustfmt --toolchain nightly-2023-09-04-x86_64-unknown-linux-gnu`

I am new to realm, can you please specify how to reproduce this error?

To reporoduce the error.
Clone the repo to your device system.
Open the project folder "realm" with VScode.

Once the projects open press Ctrl-P and search for "repo in dev container" if that option doesn't exist you'll have to install the dev containers extension in vscode.
Here's the VSCode docs just in case

https://code.visualstudio.com/docs/devcontainers/containers#_installation

VScode will take a while to build the dev container. Once the dev container finishes building navigate in the file explorer to realm > implants > imix > main.rs (or any rust file)
And press ctrl-S or File > save

This should trigger the autoformatting and raise the error as a pop up in the bottom left corner of VSCode.
If the files doesn't autoformat press ctrl-p and search for "format".
