handle_query_contract_id()

Handle explanation

The Ethereum application will call this handle to query the contract name and version to display.

The plugin needs to perform the following actions:

• Write the name of the plugin/smart contract
• Write the version

An example is already done in the boilerplate plugin. Adapt and expand it for your use case.
