Add electrs docker container to devnet start

[mijoco-btc]

Bitcoin development.

There are several attempts to run devnet/regest docker environments which incorporporate the clarinet containers (as a subset) and also include an electrs server. Electrs (or equiv) is needed to fully explore use cases on bitcoin regtest.

See for example: stacks-network/sbtc

Describe the solution you'd like Love this functionality to be part of the clarinet containers. Eg if the orchestrator could also spin up;

• electrs
• mempool-api
• optionally mempool-web (instead of existing bitcoin explorer).

Describe alternatives you've considered The alternatives are in the sBTC working stream but having this functionality in Clarinet would make it stable and available to all devs.
