Spring-ai Refactor: Replace Traditional Switch Statements with Switch Expressions

This PR refactors several components to replace traditional switch statements with the new switch expressions. This change enhances code readability, reduces the risk of fall-through errors, and allows for a more concise syntax.

Changes Made Files Updated:

AzureAiSearchFilterExpressionConverter
MilvusFilterExpressionConverter
RedisFilterExpressionConverter
RedisVectorStore
TypesenseFilterExpressionConverter
WeaviateFilterExpressionConverter

Key Modifications:

Replaced traditional switch statements with switch expressions in the listed files. Improved syntax by utilizing arrow (->) syntax for case actions, removing the need for explicit break statements. Added default cases to handle unknown message types more cleanly.

Benefits Improved Readability: The new switch expressions simplify the code structure, making it easier to follow. Reduced Errors: Eliminating fall-through behavior minimizes the potential for bugs. Direct Value Assignment: The ability to return values directly enhances code clarity and intent.
