update to new upstream CLN

ElementsProject/lightning#7258 finally merged,
so we need to switch to the new more consistent tag names and
use the elementsproject fork instead of niftynei

There are also some changes required for the new startup_regtest script.

 - [`bitcoind`](https://github.com/bitcoin/bitcoin) with `scanblocks` RPC enabled (at least v24 and `blockfilterindex=1`)
-- [`lightningd`](https://github.com/elementsproject/lightning) (aka Core Lightning aka CLN), built from [this branch](https://github.com/niftynei/lightning/tree/nifty/onchain_notif). (This branch adds the two new custom notification topics we use for Smaug: `utxo_deposit` and `utxo_spent`)
+- [`lightningd`](https://github.com/elementsproject/lightning) (aka Core Lightning aka CLN), at least version v24.08
 
 I recommend [`nix-bitcoin`](https://nixbitcoin.org) with a config [something like this](https://github.com/chrisguida/nix-dell)
-- Obviously this is for mutinynet; if you want mainnet, edit your flake url to pull in the official nix-bitcoin repo)
+- Obviously this is for mutinynet; if you want mainnet, edit your flake url to pull in the official nix-bitcoin repo.
 
 To get started quickly with nix-bitcoin, I recommend [this excellent tutorial](https://github.com/chrisguida/nixos-mutinynet-tutorial) ;).
