### Electron Forge version

7.2.0

### Electron version

28.1.0

### Operating system

Windows 10

### Last known working Electron Forge version

6.0.0

### Expected behavior

I have a custom plugin named `ResourcePlugin` -- https://github.com/cwellsx/electron-forge-resource-plugin
It's configured in `forge.config.ts` like this -- https://github.com/cwellsx/electron_forge_template/blob/dotnet/forge.config.ts

When I run `electron-forge make` then I expect its `init` function and its hook functions to be called once.

I observed this expected behaviour when I used 6.0.0 of Electron Forge.

### Actual behavior

With v7.2.0 I see the `init` function and the hook functions (not the constructor) being called twice.
The plugin therefore edits the `extraResource` property twice -- which causes a failure.
Below is a debug log file also including log messages from my `ResourcePlugin`

```
C:\Users\Christopher\Source\Repos\electron_forge_template>npm run make

> my-new-app@1.0.0 make
> set DEBUG=electron-forge&& electron-forge make

I'll edit the plugin to correct this -- i.e. to not edit the property twice -- but this bug report is FYI in case your running a plugin's methods twice isn't what you wanted to be doing -- I don't think that you documented this as new or breaking behaviour in the release notes, nor as expected behaviour in https://www.electronforge.io/advanced/extending-electron-forge/writing-plugins

### Steps to reproduce

- git clone https://github.com/cwellsx/electron_forge_template.git
- git checkout 2c53c88246c92e44709d8490e954e72bddf32331
- npm run make
