How to Setup remote branch automatically 🤖 (`push.autoSetupRemote`)

Each time I setup a branch on my localhost and attempt to push it to `GitHub`,
I get an error message similar to the following:

```sh
n@MBP auth % git push

fatal: The current branch gen-erd-#207 has no upstream branch.
To push the current branch and set the remote as upstream, use

git push --set-upstream origin gen-erd-#207

To have this happen automatically for branches without a tracking
upstream, see 'push.autoSetupRemote' in 'git help config'.
```

Need to look this up and get it configured so that it automatically creates the remote branch for me. 💭
