 * This button type renders a HTML tag <button> and takes the HTML attributes
 * name and value as additional attributes to those defined in AbstractButton.
 *
 * Since we no longer want to have any <input type="submit" /> in the TYPO3 core
 * you should use this button type to send forms
 *
 * Example:
 *
 * ```
 * public function __construct(
 *     protected readonly ComponentFactory $componentFactory,
 * ) {}
 *
 * public function myAction(): ResponseInterface
 * {
 *     $buttonBar = $this->moduleTemplate->getDocHeaderComponent()->getButtonBar();
 *     $saveButton = $this->componentFactory->createInputButton()
 *          ->setName('save')
 *          ->setValue('1')
 *          ->setIcon($this->iconFactory->getIcon('actions-document-save', IconSize::SMALL))
 *          ->setTitle('Save');
 *     $buttonBar->addButton($saveButton, ButtonBar::BUTTON_POSITION_LEFT, 1);
 * }
 * ```
