If this referenda passes the Substrate Framework version used by Cere Network will be updated to 0.9.28 represented in [Release v4.6.0](https://github.com/Cerebellum-Network/blockchain-node/releases/tag/v4.6.0).

Set the new runtime code.

# <weight>
- `O(C + S)` where `C` length of `code` and `S` complexity of `can_set_code`
- 1 call to `can_set_code`: `O(S)` (calls `sp_io::misc::runtime_version` which is
  expensive).
- 1 storage write (codec `O(C)`).
- 1 digest item.
- 1 event.
The weight of this function is dependent on the runtime, but generally this is very
expensive. We will treat this as a full block.
