Update working-with-ui-annotations-83c89cc.md

[hitesh-parmar]

This commit delivers a comprehensive rewrite of the SAPUI5 SDK documentation topic "Working With UI Annotations." The updated version reflects current best practices and SAP's strategic direction, covering:

• OData V2 support via both BOPF and RAP, including guidance on draft handling and annotations
• OData V4 integration with RAP, showcasing in-place CDS annotations and behavior definitions
• CAP model annotations, with examples using CSN/CDS syntax for Fiori elements
• A detailed comparison of annotation types (in-place, ex-place, vocabulary-based)
• Clear recommendations on using backend vs frontend annotations, with pros, cons, and use cases
• Promotion of SAP Fiori tools for annotation management, previewing, and app generation
• Migration guidance from legacy BOPF to RAP and Fiori elements

This update aims to support developers transitioning to RAP and CAP, improve annotation consistency, and encourage adoption of SAP Fiori tools for streamlined development workflows.
