Revert #23583: Ineffective TypeScript type handling in telemetry utils

[RishhiB]

The changes in #23583 for handling record access in telemetry utils didn't achieve the intended type safety improvements. While they satisfied linter rules, TypeScript still ignores undefined possibilities, leaving type analysis in these situations potentially untested.

• Removing the null coalescing operator might introduce a bug if settings[key] can be undefined. Consider keeping the null coalescing operator to handle undefined values.

return settings[key];

• [nitpick] The removal of the explicit type declaration for 'annotations' might introduce ambiguity. The type should be explicitly declared to maintain clarity.

const annotations = annotationCases[annotationCase];

packages/utils/telemetry-utils/src/mockLogger.ts:335

• The removal of the type annotation for actualValue might introduce a bug if actual can contain values that are not of the expected type. Consider keeping the type annotation to ensure type safety.

const actualValue = actual[expectedKey];

Please update the title and description - it is not that changes are "not needed". The changes don't have the desired result. They resolve the linter rule complaint, but don't change TypeScript treatment of types. TypeScript ignores the undefined possibility even when explicit. So, the analysis after that point is compromised.
