use inclusive language

[anoonan]

This PR:

1. Removes an unused config that uses language that is not inclusive. There is an issue open to rename this issue but no movement on it so removing it: Rename extension-pkg-whitelist to extension-pkg-allow-list pylint-dev/pylint#3669
2. Updates a comment to use inclusive language.
