use inclusive language and fix some lint errors

[anoonan]

What does this PR do? Updates some of our variable names and comments to use inclusive language.

I also had to fix a few linting errors in some integrations that hadn't been updated in a while.

Are there breaking changes in this PR? No, should be a no-op change.

Any background context you want to provide?

Is there parity with the server-side/android/iOS integration components (if applicable)? N/A

Does this require a new integration setting? If so, please explain how the new setting works No
