docs.go is generated as swagger 2.0

Hi,

Thanks for this project the swagger.yaml and swagger.json are generated as Open API 3.0.
However, the docs.go file looks like Swagger 2.0.

    "schemes": {{ marshal .Schemes }},
    "swagger": "2.0",
    "info": {
        "description": "{{escape .Description}}",
        "title": "{{.Title}}",
        "contact": {
            "name": "Eugene Berger",
            "url": "https://f1bonacc1.github.io/process-compose/"
        },
        "license": {
            "name": "Apache 2.0",
            "url": "http://www.apache.org/licenses/LICENSE-2.0.html"
        },
        "version": "{{.Version}}"
    },
    "host": "{{.Host}}",
    "basePath": "{{.BasePath}}",
    "paths": {
....

Is this intentional?
I couldn't find a flag to convert it to OpanAPI 3.0.

Thank you.
