@santosh-pingle made the updates based on your feedback, please have a look

Please see the comment I made in the linked issue #929 (comment)

According to the example I found here: https://build.fhir.org/ig/HL7/fhir-ips/StructureDefinition-Coding-uv-ips.html it seems the translation extension is on the display (which is a string) rather than the Coding itself (display is a field inside Coding).

If that's the case, then all we need to do is to reuse the extension function

fun StringType.getLocalizedText

which is in this file: MoreQuestionnaireItemComponents.kt

I would suggest moving that function to the common module if that's the path we decide to go down.
