[MINOR][ML][PYSPARK] ALS example cleanup
Cleans up ALS examples by removing unnecessary casts to double for `rating`
and `prediction` columns, since `RegressionEvaluator` now supports `Double` &
`Float` input types.
## How was this patch tested?
Manual compile and run with `run-example ml.ALSExample` and `spark-submit
examples/src/main/python/ml/als_example.py`.
