- Call hash for Polkadot upgrade: `0x061f7d9c2994b388cf69da9c4bef9f8c1ea1b00a66c43531f515aeacbe0a76a8`

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.
