The proposal proposes an upgrade of the Polkadot Runtime to **v9280** - Release notes, runtime changes and proposal hash can be found [HERE](https://github.com/paritytech/polkadot/releases/tag/v0.9.28). Feel free to use srtool yourself to check the proposal hash. Among other changes, this release most notably **adds nomination pools to the Polkadot runtime** - please note that these will need to be configured via governance after enactment of this runtime upgrade. 

**Runtime**

✅ audited #11918 Low - Make new storage layer truly default

✅ trivial #11690 Low - Add event to pallet asset-tx-payment

✅ audited #11796 Low - Auto-incremental collectionid

✅ trivial #11985 Low - Pallet-contracts: fix 16bit func_id

✅ trivial #11991 Low - Contracts: apply depth limit when decoding

⏳ pending non-critical audit #11819 ❗️ Medium - Transaction payment runtime api: query call info and fee details

✅ audited #11927 Low - Transactional: wrap pallet::calls directly in storage layers

✅ trivial #5582 Low - Add nomination pools to polkadot runtime

✅ trivial #5910 Low - Update weights

If passed by the Council, this proposal should be voted by the community for final decision and enacted after. Make sure to vote at your convenience!

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.
# </weight>
