feat: Add support for Playwright storageState configuration

[Samuel-StO]

This PR introduces a new storageState option in the Playwright helper configuration.
With this change, users can pass a Playwright storage state directly (either as a path to a JSON file or as an object) to initialize browser contexts with preloaded session data such as cookies, localStorage, IndexedDB, or authentication tokens.

Key points

• storageState can be configured globally in codecept.conf.js or overridden per scenario.
• Ensures Playwright handles storage state validation and errors natively.
• Simplifies authentication and session reuse across tests.

Applicable helpers:

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

Applicable plugins:

• allure
• autoDelay
• autoLogin
• customLocator
• pauseOnFail
• coverage
• retryFailedStep
• screenshotOnFail
• selenoid
• stepByStepReport
• stepTimeout
• wdio
• subtitles

Pull Request Overview

This PR adds support for Playwright's native storageState configuration to the Playwright helper, enabling users to initialize browser contexts with preloaded session data such as cookies, localStorage, and authentication tokens. The feature allows passing either a file path to a JSON storage state or a storage state object directly.

• Adds storageState configuration option to Playwright helper
• Implements grabStorageState() method to capture current browser state
• Ensures scenario-level cookies override global storageState configuration

The code block formatting is broken. The opening backticks should be on a new line after the parameter description, not inline with it.

Suggested change

	* `options.indexedDB` **[boolean][26]?** set to true to include IndexedDB in snapshot (Playwright >=1.51)```js
	// basic usage
	const state = await I.grabStorageState();
	require('fs').writeFileSync('authState.json', JSON.stringify(state));
	// include IndexedDB when using Firebase Auth, etc.
	const stateWithIDB = await I.grabStorageState({ indexedDB: true });

[nitpick] The logic for handling storageState and cookies should be more explicit. Consider extracting this into a separate method or adding a comment explaining why scenario cookies completely override storageState rather than merging.
