You’re not answering the question. Is it possible to delete or not?

On GitHub yes someone might be watching, but deletes are still possible.

I don't know. You can always clean the Git history & force-push it, but the developers would have to explain if there's any backups or archive kept anywhere...

Since data is stored permanently on Arweave, there's no way to remove it from the blockchain. However, you could force push your repo which would remove your concerned commit from Gitopia repository view.
