[mapdb] Explicitly set date format for serialization (#16657)

Browse Source 
Between Java 17 and Java 21, serialization of Date has changed due to CLDR 42 which uses a narrow non-breaking space.
To ease switching JDK versions, the serialization format is explicitly set to the Java 17 format when GsonBuilder is used.
