TYPO3 Core

During and after a successful core update in the install tool a few messages are unstyled:

• TYPO3 CMS core download finished
• Checksum verified
• Unpacking TYPO3 CMS core successful
• Moved TYPO3 CMS core to final location

All four messages are styled with the css-class alert-ok which is not present in typo3\sysext\install\Resources\Public\Css\InstallTool.css.

In typo3\sysext\install\Classes\Service\CoreUpdateService.php are four coresponding calls of "$message = GeneralUtility::makeInstance(OkStatus::class);".

When setting protected $severity = 'ok'; to protected $severity = 'success'; in typo3\sysext\install\Classes\Status\OkStatus.php the four messages get the class alert-success and are styled correct.

Maybe this is a side-effect of [[https://forge.typo3.org/issues/71374]].
