The fix will use quotes to escape "key", which is column name in the metadata table. Should work for different database types.

Part 2 of https://github.com/google/adk-python/discussions/3605.
The DatabaseSessionService now checks for the usage of a V1 schema based on the "adk_internal_metadata" table. Table creation and subsequent operations use either the V0 or V1 SQLAlchemy models accordingly. New databases will default to V1.
Migration script and CLI command will be provided in the next change.
