Lightning API docs

Continue from #673
Next steps

• We need to add support for Open API Spec on lightning. use this library https://github.com/open-api-spex/open_api_spex
• After adding that library create a demo spec eg project_controller_spec.ex to show the structure
• generate openapi.yaml file and put it in a directory that can be fetch via http request, eg static/openapi.yaml
• In docs repo use "docusaurus-plugin-openapi-docs": "^4.5.1", "docusaurus-theme-openapi-docs": "^4.5.1", to generate docs. In docusaurus.config.ts We can specify

 plugins: [
    [
      'docusaurus-plugin-openapi-docs',
      {
        id: 'api',
        docsPluginId: 'classic',
        config: {
          lightning: {
            specPath: 'static/openapi.yaml',
            outputDir: 'docs/api',
            sidebarOptions: {
              groupPathsBy: 'tag',
              categoryLinkSource: 'tag',
            },
          },
        },
      },
    ],
  ],

• It's definitely easier to generating the docs on lightning, So i will have to figure out how to fetch the openapi.yaml form lightning repo. Probably should look on adaptor generate script

Okay maybe we need to use swagdox because you get to specify the api on the function using similar syntaxt like hexdoc

defmodule MyApp.UserController do

  @doc """
  Returns a User.

  [Swagdox] API:
    @param id(query), integer, "User ID", required: true

    @response 200, User, "User found"
    @response 403, "User not authorized"
    @response 404, "User not found"

    @security ApiAuth, [read]
  """
  @spec show(any(), map()) :: nil
  def show(_conn, _params) do
    ...
  end
end

Okay i ran into couple of hiccups.
Getting Open API spec from lightning using bureaucrat package was really hard I had to switch gear and improvise a bit to generate a Postman collection instead
