Added Support for YouTube Shorts

Summary

This pull request adds support for embedding YouTube Shorts links, such as https://youtube.com/shorts/AAcP_D8fz5c?si=8r0AxKqDjrwhv8s9, which are not currently supported by the package.

Since the existing PR #111 remains unmerged and there hasn’t been any recent activity from maintainers, I created this PR to ensure that the feature can be utilized by others who need it.

I have been using this package for a long time and have generally found it to be reliable. However, my project recently required support for embedding YouTube Shorts. Due to the lack of support for Shorts links in this package, I needed to modify the code locally to meet project requirements. Given that other users might face similar needs, I decided to contribute this update to the main repository so everyone can benefit from it without needing custom workarounds.
