improvement: Typescript typings

[nikzupancic]

Motivation/Description of the PR

When using Codecept in Typescript, few typings are inconsistent with documentation:

• codecept.run() is async and should return Promise<void> instead of simply void (return value is awaited here)
• Interactive pause() should accept optional object
• executeScript and executeAsyncScript should have the ability to return values

Applicable helpers:

• Playwright
• Puppeteer
• WebDriver
• REST
• FileHelper
• Appium
• TestCafe

Applicable plugins:

• allure
• autoDelay
• autoLogin
• customLocator
• pauseOnFail

• subtitles
