Enable 4-part version number

DuckDB is using 3-part version number. Sometimes it may be necessary to
make an updated JDBC release with the changes only in JDBC/JNI code
keeping the engine version the same. For this it is proposed to add
fourth component to version number for JDBC-specific changes. So the
version is supposed to look like `v1.2.2.0`.

Testing: JAR bundling with 4-part version was tested in a separare repo.
