Json schema for vendir spec

[gberche-orange]

Describe the problem/challenge you have

It would be convenient to have coding assistance from IDE when reading/editing a vendir.yaml file

Describe the solution you'd like

Formatting the https://carvel.dev/vendir/docs/v0.34.x/vendir-spec/ as a https://json-schema.org/ and registering it into https://www.schemastore.org/json/ would automatically enable most recent IDEs (e.g. intellij, vscode) to automatically provide:

• inline doc
• completion
• static analysis

Anything else you would like to add:

Going to accept this issue.
We can add this directly into schemastore or host it in carvel.dev. My first inclination would be to host it in carvel.dev and just register that URL.

Another thing that could be interesting is to find a way to do this automatically. I saw there are a couple of libraries that generate the jsonschema directly from go structs maybe that is something that can be explored, we might need to add some docs on our structs to help with this but apart from that, it should be pretty simple.

In the first iteration, we can just add the schema manually, but it would be great if we find a way to do this automatically with our release process.
