Type definition `BasePluginOptions` property `test` should use `Rules`, not `Rule`

[Skarbo]

Bug report

Type definition BasePluginOptions has the wrong type definition Rule for properties test, include and exclude.

/** @typedef {RegExp | string} Rule */
/** @typedef {Rule[] | Rule} Rules */

/**
 * @template T
 * @typedef {Object} BasePluginOptions
 * @property {Rule} [test]
 * @property {Rule} [include]
 * @property {Rule} [exclude]
 * ...
 */

According to the documentation

type test = string | RegExp | Array<string | RegExp>;

the properties should be defined as Rules:

/**
 * @template T
 * @typedef {Object} BasePluginOptions
 * @property {Rules} [test]
 * @property {Rules} [include]
 * @property {Rules} [exclude]
 * ...
 */

Actual Behavior

When passing array of RegExp as test property in CompressionPlugin constructor, TypeScript will be unable to compile when running Webpack script with TypeScript:

error TS2322: Type 'RegExp[]' is not assignable to type 'Rule'

Expected Behavior

Expect no TypeScript errors when running Webpack script with TypeScript.

How Do We Reproduce?

// my-script.ts
const compressionPlugin = new CompressionPlugin({
  test: [ /foo/, /bar/ ],
});

ts-node my-script.ts
