Specify Bitcoind v24.0+ requirement in documentation and add version check

[MicaiahReid]

We need to specify in our documentation that a version of 24.0+ of bitcoind is required to use Chainhook to index a bitcoin node. We should update our readme and this guide: https://docs.hiro.so/chainhook/how-to-guides/how-to-run-chainhook-as-a-service-using-bitcoind

We should also add a version check on the initial RPC request to the bitcoin node to verify the correct version of bitcoind is being used by the user.

although documentation is required, it might not be enough, chainhook instances running against bitcoind prior to v23 will fail silently and that can be confusing. A version check upon starting the service will help for a better diagnose and correct execution.

@qustavo totally agree! @lgalabru and I discussed this and I totally forgot to document this in the issue 🤦 . Thanks!

My understanding is that prevout RPC field has been added on v23, what the reason behind requiring v24?

@qustavo We have some other requirements for ordhook, which uses Chainhook as a dependency.

thanks for clarifying!
