What changes were proposed in this PR?

Fixes #1931

I have moved the import of packaging.version.parse to the try-except block that geopandas is imported in, as packaging is already a dependency of geopandas

How was this patch tested?

Local test by successfully running

from sedona.spark import SedonaContext
import pyspark.sql.functions as sf


SedonaContext.create(spark)
spark.range(10).withColumn("geom", sf.expr("ST_POINT(id, id)")).show()

Did this PR include necessary documentation updates?

I am in two minds about whether packaging should be added to the package dependencies as optional.

I haven't as it stands, and other areas of the code make similar decisions e.g. geoarrow, pyarrow, pyproj are not listed as optional dependencies anywhere but are all used in the code in python/sedona/utils/geoarrow.py.

@oliverbeagley I don't think we need to add packaging to optional dependencies because it is already a required dependency of GeoPandas. And currently it is only used for checking geopandas version. If geopandas is there, then packaging should be there too
