[Companion] Get rid of HistoryDepth storage (#5996)

* remove history depth from storage and add it as config for pallet staking

* add migration to v11 for staking pallet

* revert local substrate dependency patch

* remove history depth from storage and add it as config for pallet staking

* add migration to v11 for staking pallet

* revert local substrate dependency patch

* update substrate dependencies

* update cargo lock

* update to latest substrate

* revert all changes to Cargo.lock

* cargo update -p sp-io

* mark migration job as failable
