Closing as duplicate of #6242.

I see that you renamed the repository from TaskScheduler to LightTaskScheduler since that time. The existing registration will still work because GitHub automatically sets up a redirect from the old URL to the new URL when you rename a repository.

It is a good idea to avoid a reliance on such redirects in case they might stop working at some point in the future. So you are welcome to submit a URL update request. That should be done by following the procedure described here:
