Motivation and Context
Pylint version 2.10 has a bug when trying to create its cache directory: pylint-dev/pylint#4900. This causes an error message to be displayed to students, which is confusing.
Your Changes
Description: While this was fixed in Pylint version 2.11, we're currently pinned to Pylint 2.10, so I backported the fix directly into our code for now. (It will be removed at the next major release of PythonTA.)

Testing
Verified that the pylint cache directory gets created, even when its parent directory doesn't exist.
