bug: Creating a component adds two spaces before implements OnInit

### Prerequisites

- [x] I agree to follow the [Code of Conduct](https://ionicframework.com/code-of-conduct).
- [x] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already report this problem, without success.

### Ionic Framework Version

v8.x

### Current Behavior

Creating a new component with `ionic g c new-component` automatically implements OnInit. While doing this, it adds two spaces before `implements OnInit` instead of one. This is a cli bug and of course a non blocking minor.

### Expected Behavior

Remove the extra space.

### Steps to Reproduce

- `ionic g c new-component`
- check the generated ts file

### Additional Information

_No response_

Start by running `ionic g c new-component` and inspect the generated TypeScript component, focusing on the declaration containing `implements OnInit`. Locate the CLI component-generation entry point or template responsible for that output, then verify that the generated declaration has only one space before `implements OnInit`.
