Companion to Implementing MaxEncodedLen for generate_solution_type #11032 (#5145)

* Fixing `generate_solution_type`
This is needed after changes to substrate

* `VoterSnapshotPerBlock` -> `MaxElectingVoters`

* rename `SizeBound` to `MaxVoters`

* cargo update -p sp-io

* ignore failing test

* spell-check

* fix pub OffchainRepeat
