Classes from documentation are missing in flowbite.css

This issue was previously discussed in #1113, but the problem still persists. @zoltanszogyenyi I tried all the suggested approaches, but the issue still persists. On the screen, as I understand it, the selector's edges should be rounded when the `rounded-base` class is set, but in fact they are not. <img width="430" height="108" alt="Image" src="https://github.com/user-attachments/assets/12454b4d-69f0-4511-873d-c7c8822f95e8" />
