Hi Harshita mehna

I applied your patch and confirmed that it resolved the issues about t() calls should be avoided in classes. Please look at the screenshot I attached for your reference

Thank you

The patch could apply, but the change is not correct.

       $out['git_info']['#markup'] =
-        t('<p>Current version information: %v</p>', ['%v' => $git->getApplicationVersionString()]);
+      $this->t('<p>Current version information: %v</p>', ['%v' => $git->getApplicationVersionString()]);

The last line must be indented like the second one.

Please review patch.
