fix(wasm-sdk): increment document revision for transfer transitions

When creating document transfer transitions, the code now properly increments
the document's revision number before creating the transition. This ensures
the transfer transition uses revision + 1 instead of the current revision,
which is required for proper state transition validation on the platform.
