I see this message below my repo name. Is there any way to remove it? I used template for my app for a quick start, but in current form my app doesn't look like this template, because everything changed so much. I don't see any reason why it's still there.
I had the same problem and at the time for writing this answer, there is no option of removing this from Github. So removed this tag by deleting the repository from Github and recreating a new one with the same name.
⚠️ This operation will preserve only the information stored in git, not all other Github features, i.e. issues, PRs, ... If your repository has been used for a while, this might not be the right time to do this anymore.
Specific instructions:
git fetch
git push
