This updates the instructions in the docker-compose.yml to use
"docker compose" (v2) instead of "docker-compose".
Also removing a workaround for a bug in older versions of compose,
where build-args did not properly inherit their value from the
current environment. Testing this scenario on a current version
of compose shows that that problem has been resolved:
Using this compose-file:
```yaml
services:
docs:
build:
args:
- JEKYLL_ENV
context: .
```
And this Dockerfile:
```dockerfile
ARG JEKYLL_ENV=default
FROM alpine
ARG JEKYLL_ENV
RUN echo $JEKYLL_ENV >> /result.txt
CMD cat /result.txt
```
It looks like this issue has been resolved:
Without setting the `JEKYLL_ENV` environment variable, the Dockerfile correctly uses
the default value from the Dockerfile:
```console
docker compose build
[+] Building 0.6s (6/6) FINISHED
=> [internal] load build definition from Dockerfile 0.1s
=> => transferring dockerfile: 31B 0.0s
=> [internal] load .dockerignore 0.0s
=> => transferring context: 2B 0.0s
=> [internal] load metadata for docker.io/library/alpine:latest 0.0s
=> CACHED [1/2] FROM docker.io/library/alpine 0.0s
=> [2/2] RUN echo default >> /result.txt 0.3s

=> => naming to docker.io/library/composeenv_docs 0.0s
docker compose run --rm docs
default
```
And when setting `JEKYLL_ENV`, it's used to override the default in the Dockerfile:
```console
JEKYLL_ENV=production docker compose build
[+] Building 2.6s (6/6) FINISHED
=> [internal] load build definition from Dockerfile 0.5s

=> => naming to docker.io/library/composeenv_docs 0.0s
docker compose run --rm docs

```
