fix(poly info): exclude common Python cache folders when listing bricks

[DavidVujic]

Description

Listing bricks shouldn't include common Python cache folders, like __pycache__. This PR will handle that, by checking for common cache folder names.

Motivation and Context

Fixes #65

How Has This Been Tested?

Copied a __pycache__ folder among the compontents.
Ran poetry poly info to verify it was there among bricks.
Locally installed the fix, and ran the same command. Verified the __pycache__ folder was not in the list of bricks.
