panic with no further information on bad go version

[EliRibble]

I have a project that depends on something that requires go >= 1.23. When I run gomod2nix I get a panic like:

INFO[0000] Parsing go.mod                                modPath=go.mod
INFO[0000] Downloading dependencies                      
panic: error generating pkgs:     

goroutine 1 [running]:

        /home/eliribble/src/gomod2nix/main.go:6 +0xf

That's it. What it should look like is something like this:

INFO[0000] Parsing go.mod                                modPath=go.mod                                                                                                
INFO[0000] Downloading dependencies

This doesn't happen with v1.6.0. You can run it with go run github.com/nix-community/[email protected]
