k3d: reference versions schema in k3d repo

[iwilltry42]

I'm a bit confused when it comes to handling url and versions entries.
Is url just pointing to the default? How are versions handled?
If url is the default, would you recommend to have a copy of the most recent schema file in an unversioned path, so it doesn't change?

url is the default and versions lists all the available versions. Let me know when this is ready to be merged

Some extra explanation.

Without version on Schemastore example:

schemastore/src/api/json/catalog.json

Lines 1578 to 1588 in 133eb78

	{
	"name": "Ory Hydra configuration",
	"description": "Schema for Ory Hydra configuration file",
	"fileMatch": [
	"hydra.json",
	"hydra.yml",
	"hydra.yaml",
	"hydra.toml"
	],
	"url": "https://raw.githubusercontent.com/ory/hydra/master/.schema/version.schema.json"
	},

And use multiple schemas on the remote site:
https://raw.githubusercontent.com/ory/hydra/master/.schema/version.schema.json

Remark:
An alternative for better efficiency is to use "AnyOf" instead of "OneOf".
In this way, the validators only need to validate data against schemas until the first schema matches. Put the most popular version at the top (normally the latest version) and less popular version at the bottom of the list.
