 * polkadot-sdk dependency updated to partnerchains-stable2407 (stable2407 is v1.15.0 in the previous scheme)
-* remove Relay docker build files
 * changed the inner type of `McBlockHash` from Vec to an array
 * ETCM-7985 - bumped `partner-chains-smart-contracts` version and updated the `partner-chains-cli`
 to match. Now `partner-chains-cli` passes a network parameter to `sidechain-main-cli` where necessary.

 * governance authority key hash is now calculated in `prepare-configuration` without using external `cardano-cli`
