Tenderly testing for cross-chain proposals

[clemsos]

It will be good to automate the simulation of the calls we send across the Connext bridge by scripting with tenderly forks.

We can create forks with the following then get URLs and end calls there

CHAIN_ID=10
BEARER=<api token>
curl -X POST https://api.tenderly.co/api/v1/account/clement-unlock/project/project/fork -d '{"network_id": "$CHAIN_ID", "alias": "$CHAIN_ID proposal test", "description": ""}' -H "Authorization: Bearer $BEARER" -H "Content-Type: application/json"
