Fix handling of disabled state for button component
>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3559393. --> Reported by: [pameeela](https://www.drupal.org/user/1431110) Related to !133 !132 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> <p>The disabled state for the button component is a bit confusing, the setting only works if there is no link set, which is not really expected. Also, the styling needs work because the contrast of the text on the background is not sufficient.</p> <p>Instead of setting the button to disabled if the toggle is on AND there is no link, use the disabled rendering if disabled is true.</p> <p>Screenshot of styles before:<br> <img src="https://www.drupal.org/files/issues/2025-11-22/Screenshot%202025-11-22%20at%205.46.36%E2%80%AFpm.png" alt=""></p>
