[TASK] Different Base options for creating AVS Blueprints (ECDSA/BLS)

[Tjemmmic]

Overview

When a developer is creating a Blueprint, we want the developer to be able to choose between targets. Each target will change the "starting point" of the generated blueprint.

gadget blueprint create --avs bls
gadget blueprint create --avs ecdsa

Checklist

• ECDSA Template
• BLS Template

@shekohex Something like this had been discussed in the past. Let me know your thoughts here, though. Feel free to edit this completely, as well.

And Eigenlayer (--protocol eigenlayer or --protocol tangle [default])

That's for the CLI, we can add the protocol as an option.
For the template, that's easy, we could configure it to have different bases. I will work on adding support to EL on the template.
