Typo for 'Operation: charge-item-create' POST pattern

[laeccan]

In content/millennium/r4/financial/general/charge-item.md documentation content, the pattern
POST /ChargeItem/:id/$create
incorrectly includes :id in the URL.

The Example Request
POST https://fhir-ehr.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/ChargeItem/$create
correctly omits :id in the URL.
