fix: remove unnecessary line break in prompt (#70933)

Unnecessary line break after `?`

Current:

```
$ ... upgrade
? 
The following codemods are recommended for your upgrade. Would you like to apply them?
```

Expected:

```
$ ... upgrade
? The following codemods are recommended for your upgrade. Would you like to apply them?
```
