Type file id with builtins

[WilliamBergamin]

Summary

This is a copy of #237 the feature release was pushed, I therefore reverted the changes in order to allow other contributions to main

This PR introduces the new slack type slack#/types/file_id and update the slack functions to use this new type.

Had to also modify he generation script to improve the robustness of the generated tests

testing

1. Add https://raw.githubusercontent.com/slackapi/deno-slack-sdk/type_file_id_with_builtins/src/ as the value of deno-slack-sdk/ in the import_map.json of a project
2. Build a workflow that uses the new feature example

import { DefineWorkflow, Schema } from "deno-slack-sdk/mod.ts";

const ImageWorkflow = DefineWorkflow({
  callback_id: "post_image",
  title: "Workflow to post an image",
  description: "A workflow that post an image in the channel it is invoked",
  input_parameters: {
    properties: {
      interactivity: {
        type: Schema.slack.types.interactivity
      },
      channel: {
        type: Schema.slack.types.channel_id,
      },
    },
    required: ["channel", "interactivity"],
  },
});

const getImageStep = ImageWorkflow.addStep(
  Schema.slack.functions.OpenForm,
  {
    title: "Submit this form",
    interactivity: ImageWorkflow.inputs.interactivity,
    fields:{
      elements: [{
        title: "Enter a file",
        name: "image",
        type: Schema.types.array,
        maxItems: 1,
        items: {
          type: Schema.slack.types.file_id,
        },
      }],
      required: ["image"],
    }
  },
);

ImageWorkflow.addStep(Schema.slack.functions.SendMessage, {
  channel_id: ImageWorkflow.inputs.channel,
  message: "cool image bro",
  files: getImageStep.outputs.fields.image
});

export default ImageWorkflow;

3. Everything should run as expected

Special notes

Ensure your app has the files:read scope, since this is required for the feature and logged error is cryptic

Requirements

• I've read and understood the Contributing Guidelines and have done my best effort to follow them.
