Fix 4696 by updating lodash import to be direct import

[heath-freenome]

Reasons for making this change

• Fixes Named export 'isEqual' not found when using 6.0.0-beta.12 #4696 by updating the lodash import from import { isEqual } from 'lodash'; to import isEqual from 'lodash/isEqual'; so that the tsc-alias reducer updates it
• Updated the CHANGELOG.md accordingly
