    | reject CreatedSince
```
or
```bash
./make.rs container list --json
    | from ndjson

    | into filesize Size VirtualSize

```

## changelog
- transform options of `container` to sub-subcommands
  - `container` --> `container build`
  - `container --login` --> `container login`
  - `container --push` --> `container push`
- add `container list` to print the local images for the GitLab and GitHub repositories
  - `container list` will print in a pretty table
  - `container list --json` will print as NDJSON, i.e. one image per line as JSON
- use wrappers around `nob::run_cmd_as_vec_and_fail!`
  - `extend_and_run` to run a partial command with an extra vector of args
  - `extend_and_run_and_capture_silent` to run a partial command with an extra vector of args and silently capture the stdout into a string
  - this allows to get rid of the `#[rustfmt::skip]` _directive_ on `main` and format the code not too aggressively
