Custom Upgrade Path

## Proposal to Insert Custom Upgrade Path to SNS-W
### Proposer: DFINITY Foundation
### Target SNS Governance Canisters: All
---
This proposal will change the upgrade path to use different WASMs, but WASMs that are already available on SNS-W.

All SNS upgrade paths (without their own overrides) will be affected by this proposal.

## Rationale

Mitigating an issue caused by a previously published version of SNS Governance that prevented Dragginz to upgrade. This proposal provides a custom upgrade path for SNSes to skip the bad version (SNS Governance d6fb78613a9991d0387abfb6bf999d3e9ebec0f729f23d9fd2727cd5aeeaba45). See the forum post for more details: https://forum.dfinity.org/t/investigating-recently-failed-sns-upgrade-proposals/26429.

## Useful background

To see what the upgrade path currently is, run:
```
dfx canister --network ic call --candid ic/rs/nns/sns-wasm/canister/sns-wasm.did \    qaa6y-5yaaa-aaaaa-aaafa-cai list_upgrade_steps \    '(record {limit = 0: nat32; })'
```
