 * Updates the state of the avm versions depending on the current block number.
 *
 * This method will ensure that any avm versions that are enabled but which are prohibited to
 * be enabled at this block number will be shutdown and disabled.
 *
 * It will also ensure that the avm version that is considered the canonical version at this
 * block number is enabled and that its avm is started.
 *
 * @implNote The projectRootPath is the path to the root directory of the aion project. This is
 * required so that we can find the resources to load.
 *
 * @param projectRootPath The path of the project root directory.
 * @param currentBlockNumber The current block number.
 * @param enableCoinbaseAddressLocking The flag to enable the coinbase addresslock
 * @return the version of the avm to use for the given block number.
