extend schema cannot parse maps in arguments

[kzlsakal]

Environment

• Elixir version (elixir -v): Elixir 1.14.0 (compiled with Erlang/OTP 25)
• Absinthe version (mix deps | grep absinthe): 1.7.1
• Client Framework and version (Relay, Apollo, etc): n/a

Expected behavior

Extending the schema with the link directive and its arguments should result the following SDL output:

schema @link(url: "https:\/\/specs.apollo.dev\/federation\/v2.0", import: ["@key", "@tag", {name: "@override", as: "@replace"}]) {
  query: RootQueryType
}

type RootQueryType {
  hello: String
}

Actual behavior

The map is eventually supplied to Absinthe.Blueprint.Input.parse/1 but in AST format, therefore we get the following compile-time error:

(FunctionClauseError) no function clause matching in Absinthe.Blueprint.Input.parse/1    
    
    The following arguments were given to Absinthe.Blueprint.Input.parse/1:
    
        # 1
        {:quote, [closing: [line: 37, column: 36], line: 37, column: 10], [{:%{}, [closing: [line: 37, column: 35], line: 37, column: 17], [name: "@override"]}]}

        def parse(+value+) when -is_binary(value)-
        def parse(+value+) when -is_boolean(value)-
        def parse(+value+) when -is_list(value)-
        def parse(+value+) when -is_map(value)-

Relevant Schema/Middleware Code

defmodule MacroSchemaWithRenamedDirectives do
  use Absinthe.Schema

  extend schema do
    directive :link,
      url: "https://specs.apollo.dev/federation/v2.0",
      import: ["@key", "@tag", %{name: "@override", as: "@replace"}]
    end

  query do
    field :hello, :string
  end
end

Additional Information

• Trying a keyword list instead of a map yielded a similar error when the parse function received a tuple of {:name, "@override"} for the first item.
• Trying a string literal doesn't work because the spec expects an object - related docs.
• Removing %{name: "@override", as: "@replace"} from the import argument in the example code results in a successful compilation as expected.
