behave_ext.cucumber_json:PrettyCucumberJSONFormatter is unknown

[slequeux]

On a freashly cookie-cuttered project, I ran make bdd target, but it failed.

$make bdd
poetry run behave features --format=behave_ext.cucumber_json:PrettyCucumberJSONFormatter -o cucumber-report.json --format=pretty
usage: behave [options] [ [DIR|FILE|FILE:LINE] ]+
behave: error: format=behave_ext.cucumber_json:PrettyCucumberJSONFormatter is unknown
make: *** [bdd] Error 2

In my environment, I already ran `make setup-dev-host` and `make setup-dev-env-full` to gat all dependencies.
