In PySpark shell, if you call `SparkSession.builder.getOrCreate` as below:
```python
import warnings
from pyspark.sql import SparkSession, SQLContext
warnings.simplefilter('always', DeprecationWarning)
spark.stop()
SparkSession.builder.getOrCreate()
```
it shows the deprecation warning as below:
```
/.../spark/python/pyspark/sql/context.py:72: DeprecationWarning: Deprecated in 3.0.0. Use SparkSession.builder.getOrCreate() instead.
DeprecationWarning)
```
via d3304268d3/python/pyspark/sql/session.py (L222)
We shouldn't print the deprecation warning from it. This is the only place ^.

### Does this PR introduce _any_ user-facing change?
Yes, it won't show a deprecation warning to end users for calling `SparkSession.builder.getOrCreate`.
