Eliminate all Instances of `Weight::zero()`

• Added benchmarks instead of Weight::zero() placeholders.
• Added a missing benchmark in pallet_universal_dividend.
• Regenerated weights for all pallets.
• Added commit f1c396107a2312e5e029a5fe8e36f05234fc2511 to Duniter Substrate to fix pallet_balance WeightInfo.
