fix(vscode): Keep HOME variable when starting VSCode (#2694)

## Summary

Removing the HOME variable has adverse effects on many tools, most
notable git. Without it, tools can't find the configurations.

## How was it tested?

- Overrode the derivation and applied the patch
- Restarted VSCode
- Triggered the "Reopen in devbox shell" action
- `echo $HOME` in the shell
- Make this commit with the opened VSCode
