Add option to pass storage config to polars lazy read

[johannesq23]

Feature Request / Improvement

I was not able to use the table.to_polars() method because there is no option to include a storage_options param which is mentioned in the polars docs.

+1 it feels like here

iceberg-python/pyiceberg/table/__init__.py

Lines 1552 to 1560 in c5c0993

	def to_polars(self) -> pl.LazyFrame:
	"""Lazily read from this Apache Iceberg table.
	Returns:
	pl.LazyFrame: Unmaterialized Polars LazyFrame created from the Iceberg table
	"""
	import polars as pl
	return pl.scan_iceberg(self)

storage options should default to self.io.properties
