User metadata not propagated from child workflow command to child workflow's execution config

[cretz]

Expected Behavior

Like start workflow, I would expect start child workflow user metadata to end up on the execution config on the child workflow.

Actual Behavior

The user metadata only ends up on the event, not the actual child workflow

See #5857 where user metadata propagation was added.

I found the comment in the Go SDK related to this issue in private fields:

		// TODO(cretz): Expose once https://github.com/temporalio/temporal/issues/6412 is fixed
		staticSummary string
		staticDetails string

Those are fields in the ChildWorkflowOptions struct.
