[Warning] Replace distutils.spawn.find_executable with shutil.which

[santigandolfo]

The package distutils is deprecated and slated for removal in Python 3.12. We are using the function find_executable that belongs to that package. We should instead be using which from the package shutil.

Therefore we should make the change from
from distutils.spawn import find_executable
to
from shutil import which

sagemaker-python-sdk/src/sagemaker/local/image.py

Line 33 in 98bbea6

from distutils.spawn import find_executable

And the change from
if find_executable("docker-compose") is None:
to
if which("docker-compose") is None:

sagemaker-python-sdk/src/sagemaker/local/image.py

Line 90 in 98bbea6

if find_executable("docker-compose") is None:

I think this can be considered closed with #4837 @santigandolfo?

This is resolved as of this PR - #4837
