Adding cw-orchestrator to beaker

[Kayanski]

This PR aims at adding cw-orchestrator directly into beaker.

We added cw-orch into the cw-minimal-template as well.

You can find the docs for this library here : https://orchestrator.abstract.money/

This library empowers users with their smart-contracts and allows them to script, test and more using a single intuitive syntax and without leaving the Rust programming language.

With this template, cw-orch integration has never been easier. The generated interface is available directly inside the template tests. An example test syntax can be found in the src/interface.rs file.
