Describe the bug
hapi-fhir-cli returns the following error when uploading ICD10: .InvalidRequestException: HTTP 400 : HAPI-1769: CodeSystemVersion is null

To Reproduce
Steps to reproduce the behavior:

1. Download ICD 10 (I use the french edition here: https://smt.esante.gouv.fr/terminologie-cim-10/)
2. Run the command against my local server hapi-fhir-cli upload-terminology -d ./dat/cim10fr2024syst_claml_20231215.xml -v r5 -t http://localhost:9090/server/DEFAULT -u 'http://hl7.org/fhir/sid/icd-10'
3. Get the error

Expected behavior
All terms should be integrated

Screenshots

Environment (please complete the following information):

• HAPI FHIR: 7.2.2
• OS: Windows

Additional context
The service fails when checking the version of child terms.
In TermCodeSystemStorageSvcImpl class, I this this:

		for (TermConceptParentChildLink next : theConcept.getChildren()) {
			next.setCodeSystem(theCodeSystemVersion);
			retVal +=
					validateConceptForStorage(next.getChild(), theCodeSystemVersion, theConceptsStack, theAllConcepts);
		}

next.getChild() has a method getCodeSystemVersion() which returns null. This cause the issue.
The next.setCodeSystem(theCodeSystemVersion); does not change the child's version.
Calling next.setCodeSystem(theCodeSystemVersion); would solves the problem.
