Update docker-compose up to docker compose up in examples

[gitressa]

In many examples, this syntax is used:

docker-compose up

...but in Composer V2 (released April 2022), this changed to:

docker compose up

... so you get this error:

$ docker-compose up
-bash: docker-compose: command not found

Since Composer V2 is the latest official release, I think the examples should use the docker compose up syntax in these files: https://github.com/search?q=org%3Adocker-solr%20%22docker-compose%20up%22&type=code
