Discussed Refactors

[f-gate]

Changes:

• Change pallet_proposals vote to pass on milestones to 50%
• Change dispute completion requirement to 50% - cancelled

To do so:

• Update pallet_disputes::Config to include the a new item called PercentForDisputeToPass - Cancelled as it will finalise at the end of its period giving success if majority voted yest and failure if majority voted no.
• Use the new config in the pallet code
• update test + benchmark code.

No migration needed as just a config item.
Benchmarks should be re run.
