🐛 Bug: cli gives confusing `npx` command instructions

### Bug Report Checklist

- [x] I have tried restarting my IDE and the issue persists.
- [x] I have pulled in the newest version of the project.
- [x] I have [searched for related issues](https://github.com/JoshuaKGoldberg/create-typescript-app/issues?q=is%3Aissue) and found none that matched my issue.

### Expected

This is my first time using the cli to create a repo, rather than the template button on the UI (wanting the repo settings features), and all it did was create the repo locally.

### Actual

It didn't set anything up on GitHub. It left this message about running `npx index.js --remote`, which I thought was strange, since , if there was an index.js file, I would expect the command to be `node index.js --remote`, not `npx`. Nonetheless, I tried both and both failed to do anything.

### Additional Info

_No response_

Start by reproducing the CLI flow described in the issue and inspect where the `npx index.js --remote` instruction is generated. Verify what the local and remote setup commands actually do, then update the instruction so a first-time user can run the intended command successfully and confirm the behavior with the CLI flow.
