Cannot use the new structure of .devcontainer directory

[corebreaker]

The new standard in DevContainer allow to have several files devcontainer.json in subdirectories of .devcontainer directory.

The arguments --name and --path cannot be used.

For example:

.
├── .devcontainer
│   ├── context1
│   │   └── devcontainer.json
│   └── context2
│       └── devcontainer.json
