ink! Analyzer: Retroactive funding for ink! 4.x to 5.0 migration features, and other major improvements (56,750 USDT)

- The Polkadot Fellowship has a new feature called `spend()`.
- This feature allows different types of payments in cryptocurrencies like DOT and USDT.
- It was added with the Polkadot Runtime 1.1 upgrade.
- The goal is to test the `spend()` feature by sending Alice and Bob 69 USDT, which is a funny number.
- Changes include faster payments and the ability to pay in stable currencies.
- The test showed some instructions were incorrect, which could lead to errors.
- The payment goes to a company account called Polkalytics.
- This proposal is being carefully reviewed to fix any issues before going live.

The proposal aims to raise awareness and test the new `spend()` extrinsic introduced by the Polkadot Fellowship, which supports multi-asset Treasury spends from an XCM multi-location to be paid out at a specific block. The proposal suggests sending 69 USDT to Alice and Bob's Polkalytics account to test the extrinsic. No timeframe or additional resources are mentioned.
