Latest CLN defaults to wumbo now. PeerSwap's wumbo / large-channels check is broken.

$ lightning-cli --signet peerswap-swap-out 140490x1x0 246942696 lbtc                                                                                      
{
   "code": -1,
   "message": "swap amount is 246942696000: need to enable option '--large-channels' to swap amounts larger than 2^32 msat"
}

$ cat ~/.lightning/config
signet
plugin=/home/user/.lightning/signet/plugins/peerswap
daemon
log-file=logs
log-level=debug

large-channels is missing, so PeerSwap considers it turned off and won't allow the swap to continue past that check.

Even adding large-channels to the CLN config does not help.

Commenting this line out allows the swap to continue:

peerswap/clightning/clightning.go

Line 187 in c22211a

return fmt.Errorf("swap amount is %d: need to enable option '--large-channels' to swap amounts larger than 2^32 msat", amtMsat)

My PR to upgrade cln on nix go merged NixOS/nixpkgs#270897 . We can update the tests now to find out what else is broken.
Note: the --enable-developer flag got retired so there are no developer builds anymore. Developer features are enabled by the the --developer runtime option. We need to update the tests to do so.
