fix(kafka): Make parsing partitionLimitation more resilient against ws

[AndreasBergmeier6176]

Ignores whitespaces in partitionLimitation.
Fix a spelling mistake on the way.
Add a few more tests cases.
Note that currently it is not possible to configure a limitation so that
no partition will be consumed!

Thanks for the contribution!
After adding some test cases, other test (TestKafkaGetMetricSpecForScaling) is failing because it uses the data by position. Could you update it too? Basically you will need to adjust these indexes https://github.com/AndreasBergmeier6176/keda/blob/resilient_pl/pkg/scalers/kafka_scaler_test.go#L175-L179 (I think that changing 8 with 10 will be enough)
