Failing to mount directories sourced through localEnv

Hello 👋,
I'm encountering difficulties on mounting directories while relying on `localEnv` variables expansion.
I've produced a minimal example based on [the documentation's example](https://code.visualstudio.com/remote/advancedcontainers/add-local-file-mount).
I've made a folder with just the `.devcontainer/devcontainer.json` file, with the following content:
```json
{
"name": "Go Dev Env",
"image": "golang:1.20.4",

"mounts": [
"source=${localEnv:HOME}${localEnv:USERPROFILE},target=/host-home-folder,type=bind,consistency=cached"
]
}
```

My environment is:
- Win10 19045
- VSCode 1.78.2
- Remote Development v0.24.0
- Dev Containers v0.292.0
- WSL 1.2.5.0
- Docker 20.10.12
- Ubuntu-20.04 image

This is the produced log:
```
