langstream python run-tests should quote all arguments

[ddieruf]

I am able to create this which is not real great form.

docker run --rm --entrypoint /bin/bash -w /code/application/python -v /mnt/c/Users/david/source/ddieruf/AI Stories/EP1 - Smart Logs/Vector Store  and Search/langStream/./application:/code/application --env-file ./env ghcr.io/langstream/langstream-runtime-tester:0.5.6

This would be better

docker run --rm --entrypoint "/bin/bash" -w "/code/application/python" -v "/mnt/c/Users/david/source/ddieruf/AI Stories/EP1 - Smart Logs/Vector Store  and Search/langStream/./application":"/code/application" --env-file ./env ghcr.io/langstream/langstream-runtime-tester:0.5.6
