In case anyone is curious, I extracted the bech32 representation of the public keys from the genesis.json using this script:

package main

import (
	"fmt"

	_ "github.com/gnolang/gno/gno.land/pkg/gnoland"
	"github.com/gnolang/gno/tm2/pkg/bft/types"
)

func main() {
	path := "../gno/misc/deployments/test4.gno.land/genesis.json"

	doc, err := types.GenesisDocFromFile(path)
	if err != nil {
		panic(err)
	}

	for _, v := range doc.Validators {
		fmt.Printf("Name: %s\n", v.Name)
		fmt.Printf("Address: %s\n", v.Address)
		fmt.Printf("PubKey: %s\n", v.PubKey.String())

		fmt.Printf("\n===========================\n\n")
	}
}
