devcontainer process exited with exit code 1 followed by compressed JavaScript gibberish is not very help to understand problem

When I attempted to create a new GitHub codespace from https://github.com/enola-dev/enola/pull/518,

please note that I am filing this problem using the original first commit 0637b590347653481c7675fa3fc94e88b4a58cdc of that PR, but will shortly be amending the PR with further experimentation, the initial `.devcontainer/devcontainer.json` [looked like this](https://github.com/enola-dev/enola/blob/0637b590347653481c7675fa3fc94e88b4a58cdc/.devcontainer/devcontainer.json), with all comments removed, just for brevity:

```json
{
"name": "Enola.dev's Dev Containers.dev",

"image": "mcr.microsoft.com/devcontainers/universal:2-linux",

"onCreateCommand": "/workspaces/enola/test.bash",

"features": {
"ghcr.io/devcontainers-community/features/bazel:1": {
"bazelisk_version": "v1.19.0"
},

"ghcr.io/devcontainers/features/java:1": {
"version": "21",
"installMaven": "false",
"installGradle": "false"
}
},

"hostRequirements": {
"cpus": 16
}
}
```

it failed like this - and I thought this compressed JavaScript gibberish log was "not very helpful" to understand problem:

[Here is the ful log](https://github.com/devcontainers/spec/files/14351648/codespace-failure.txt).

Perhaps you would consider making this more end-user friendly, and print some more understandable root cause of the failure?

Empieza reproduciendo el fallo con el archivo .devcontainer/devcontainer.json referenciado y el comando devcontainer up; después, inspecciona el registro completo enlazado alrededor del fallo en devContainersSpecCLI.js. Se considera terminado cuando la CLI muestra una causa raíz concisa y comprensible en lugar de una salida de JavaScript comprimida, y el fallo existente se sigue notificando correctamente.
