Twitter fix 2

[murdercode]

This pull request includes significant updates to the TwitterShortcode class in the src/Shortcodes/TwitterShortcode.php file. The changes primarily focus on improving the method for fetching oEmbed data from Twitter by switching from cURL to Guzzle HTTP client and adding error handling with retries.

Enhancements to oEmbed data fetching:

• Added Guzzle HTTP client and related exceptions to handle HTTP requests.
• Replaced the cURL implementation with Guzzle HTTP client in the getOembed method to improve reliability and maintainability.
• Implemented retry logic in the getOembed method to handle intermittent 404 errors from Twitter, enhancing the robustness of the data fetching process.
