feat: add json schema for manifest

[melotic]

Adds a JSON Schema for the Manifest format. Generated with JSON.NET Schema

using Microsoft.ComponentDetection.Contracts.BcdeModels;
using Newtonsoft.Json.Schema.Generation;

var generator = new JSchemaGenerator();
var schema = generator.Generate(typeof(ScanResult));

// Add meta schema
schema.ExtensionData.Add("$schema", "http://json-schema.org/draft-07/schema#");

Console.WriteLine(schema.ToString());

Part of #570

Do you intend this to be manually or automatically maintained? Cause that will affect how I review this.

I think as part of CI we should run that small C# program and diff the output. If the JSON schema changed, fail the build? Sort of like how ADO fails if the generated SQL stuff isn't part of the commit.

Should I include the script and CI to check that the schema is properly updated? I'll follow up with a PR to update our validation tests to also ensure the schema is followed.

I'll approve this now, and feel free to followup in another PR, or open an issue in our backlog.
