bug: info generators choke on %{}

Describe the bug

When I try to use the info generator like so:

defmodule Pyro.Info do
  @moduledoc "Introspection for pyro."

  use Spark.InfoGenerator, extension: Pyro.Component, sections: [:global, :components]

I get the following error:

error: invalid quoted expression: %{}

Please make sure your quoted expressions are made of valid AST nodes. If you would like to introduce a value into the AST, such as a four-element tuple or a map, make sure to call Macro.escape/1 before

Runtime

Elixir v1.17.0-rc.1 (OTP 27) Erlang 27.0 OS Arch BTW Spark 2.1.24

Additional context

I suspect it could either be related to this schema that is an option on all sections/entities:

defmodule Pyro.Schema.Variable do
  @moduledoc false

  @schema [
    type: {:map, :atom, :any},
    default: %{},
    doc: "variables to merge into scope"
  ]
  @doc false
  def schema, do: @schema
end

Or possibly this struct property default that I add to all entities:

  defstruct [
    # ...
    variables: %{}
  ]

Those are the only ways I'm using %{} in the schema.
