Create a list of supported and unsupported sites for the README

[yanirmr]

Description:
Currently, the extension is designed to work on a specific set of websites. It would be helpful for users to have a clear list of which websites are supported and which are not, allowing them to easily identify if the extension will meet their needs.

In order to provide this information, we need to create a comprehensive list of supported and unsupported sites and include it in the project's README file.

Tasks:

1. Review the current extension code to identify the websites on which it is designed to work.
2. Test the extension on a variety of websites to verify its compatibility and proper functioning.
3. Compile a list of supported websites, including the website name and URL.
4. Identify any popular websites where the extension does not function as expected and compile a list of unsupported websites.
5. Update the README file with the lists of supported and unsupported websites, along with any known limitations or issues specific to certain sites.

Acceptance Criteria:

• The README file should contain a clear and comprehensive list of supported and unsupported websites.
• Any known issues or limitations specific to certain websites should be documented in the README file.
• The list should be easily understandable and accessible to users who are considering using the extension.

Notes:

• Please ensure that the list is organized and easy to read, possibly using a table format or bullet points.
• If any issues or limitations are discovered during the testing process, please document them and provide possible solutions in the comments section of this issue.
