Refactor chat memory repository artifacts for clarity

 - Rename the artifact ID of the chat memory repository artifacts:

    - `spring-ai-model-chat-memory-jdbc` -> `spring-ai-model-chat-memory-repository-jdbc`
    - `spring-ai-model-chat-memory-cassandra` -> `spring-ai-model-chat-memory-repository-cassandra`
    - `spring-ai-model-chat-memory-neo4j` -> `spring-ai-model-chat-memory-repository-neo4j`

 - Rename the package names to include "repository". Example: org.springframework.ai.chat.memory.repository.jdbc.JdbcChatMemoryRepository
    - This package renaming also requires to change the default schema location for the jdbc repository to include "repository"
      - Update the docs

 - Update the artifact IDs in the parent POM, BOM, autoconfiguration and starters
 - Update upgrade notes and docs to describe the changes
