Avoid adding problematic lines to requirements.txt

kedro is preinstalled in the behave environment,
so this should not be needed.
In exchange, requirements.txt files can always be read
by setuptools automatic parsing.

See McK-Private/private-kedro#352 (comment)
for motivation of the original logic.
