Problem/Motivation
As suggested by @heddn in #1835754-46: Add last 'changed' property to user entity, now that D7 has a "changed" property on user entities, D9 should have the ability to include that in migrations from D7.
Steps to reproduce
Do a migration from D7.83 or later.
Proposed resolution
Add the "changed" property to D9's D7 migration code, ensuring that it's optional as older version of D7 will not have it.
