[BiscuitWallet]

Updates the Biscuit Wallet entry (added in #2264) to the current version, 1.2.2:

• Description: multi-crypto, swaps now work over Tor through exchanges that never ask for KYC.
• Tracked data: Trocador's IP logging applies outside Tor mode only; nothing is recorded for swaps through Biscuit's own exchanges or for atomic swaps.
• Third-party dependencies: PegasusSwap, ETZ-Swap and Stereoswap; Ethereum, Arbitrum and Solana nodes, Blockscout.
• Ecosystems and assets: Ethereum, Solana, ETH, USDT, USDC, SOL; Litecoin and Dogecoin as other.
• Twitter link added.
• Funding: donations (https://biscuitwallet.com/donate/).
• Whitepaper: https://biscuitwallet.com/whitepaper/ (also as PDF).

Thank you for listing Biscuit!
