// To upgrade Pyth, take the following steps.
// 0. Make contract changes in the "contracts" folder. These updated contracts will be posted on chain as an
//    entirely new package. The old package will still be valid unless we "brick" its call-sites explicitly
//    (this is done for you via the version control logic built into the Pyth contracts).
// 1. Make sure that in version_control.move, you create a new struct for the new version and update the
//    current_version() and previous_version() functions accordingly. The former should point to the new version,
//    and the latter should point to the old version.
// 2. Update the Move.toml file so that it points to a wormhole dependency whose Move.toml file has a "published-at" field
//    specified at the top with the correct address.
// 3. Execute this script!
