Enhance OpenAPI Content Fragment for List Fragments

[#1]

Request for Feature Enhancement (RFE) Summary:	Enhance Content Fragment OpenAPI for List Fragments to include eTag
Use-case:	List Content Fragment documentation reads, API would return `etag`. But when testing against AEM, the etag field is missing in response. This leads to a problem when updating CF, we dont have CF etag to pass into If-Match header. So update CF requires 3 trips: Find CF ID using List Find etag using Get Edit CF using Patch Fixing List CF API to return eTag will reduce UpdateCF to 2 trips
Current/Experienced Behavior:	List CF API is NOT returning eTag in response
Improved/Expected Behavior:	List CF API must return eTag in response
Environment Details (AEM version/service pack, any other specifics if applicable):	AEMaaCS
Customer-name/Organization name:	SGWS
Screenshot (if applicable):	provided above
Code package (if applicable):
