'webpack-preprocessor': project is missing dependency '@types/bluebird'

[samijaber]

Current behavior

Cypress project type-checking fails if we try to type-check cypress/plugins/index.js and it includes require('@cypress/webpack-preprocessor')

Desired behavior

Type-checking succeeds

Test code to reproduce

// This function is called when a project is opened or re-opened (e.g. due to the project's config
// changing).
// read more: https://on.cypress.io/plugins-guide

const webpackPreprocessor = require('@cypress/webpack-preprocessor');

/** @type {Cypress.PluginConfig} */
module.exports = (on, config) => {
  on(
    'file:preprocessor',
    webpackPreprocessor({
      webpackOptions: {},
    }),
  );
  return config;
};

Versions

Introduced in https://github.com/cypress-io/cypress-webpack-preprocessor/pull/83/files#diff-dcdc3e0b3362edb8fec2a51d3fa51f8fb8af8f70247e06d9887fa934834c9122R2 (merged in v5.2.1)

From looking around, it seems that @types/bluebird is not provided as a dependency in any of the cypress packages. It seems weird to me that users need to figure out on their own that this dependency is needed. If usage of @cypress/webpack-preprocessor requires a @types/ module to type-check, I would expect it to be in dependencies and installed automatically.
