Outdated weaviate version in contextionary newspublications example

[dobraczka]

Hello,
thanks for this nice repository of examples!
I wanted to test Weaviate with a quick example that runs fast on the CPU and does not require API keys, so I had a look at the contextionary newspublications example. Apparently the version in the docker-compose.yml is too old to work with an up-to-date client leading to the following error:

weaviate.exceptions.WeaviateStartUpError: Weaviate version 1.9.0 is not supported. Please use Weaviate version 1.23.7 or higher.

I managed to easily fix this by updating the docker-compose.yml. I submitted a PR with my proposed fix.
