Create a schema for syntax highlighting of Maestro YAML files in IDEs

[edgarlealbd]

As of now, we can't know if Maestro YAML flow files are okay or not via IDE IntelliSense, but only when running maestro test. I propose to create a maestro-schema.json file that provides the IDE with IntelliSense to display errors at coding time.

For example: the following flow wouldn't get flagged by the API as an invalid maestro flow, as foo and xoo are not valid maestro commands:

appId: com.company.app
---
- foo:
    xoo: bar

Here's the URL to a example provided by Codemagic CI to help devs with their codemagic.yaml file: Codemagic schema

Here's how it looks otherwise:
