GhApi.repos.delete_repo_secret does not work

There are 2 issues here.
1. The signature of the function `delete_repos_secret` is confusing. The API doc says that it takes 3 parameters `owner`, `repo` and `secret_name` while the `help` function says that it takes 2 parameters `repo` and `secret_name`.
2. I tried to call `delete_repos_secret` with both 2 and 3 parameters but neither of them work. BTW, the GitHub cli tool `gh` works well on this.
