Geo: Use more consistent keyword args for Replicators

What does this MR do?

Consistently use the same keyword args to pass data needed to instantiate Replicators.

This change would cause some transient job failures if the feature were in use. But it is safe now because it is still feature flagged and under development.

Closes #218592 (closed)
