Issue1632 remove images (#1645)

* Implemented PdfImageRemovalService.java and PdfImageRemovalController.java. Image can be removed testing using Postman, but the file size doesn't change.

* Fix removal logic in service file to decrease file size.

* Implement "Remove Image" feature on the website

Updated the front-end code to integrate the "Remove Image" feature. The new functionality is now fully operational on the website, allowing users to remove images as expected.

* Add comments to PdfImageRemovalController and PdfImageRemovalService.

* Change the google material icon in navbar, homepage and remove-image-pdf.html.
