Subject: [PATCH] fix(testing): use correct server process reference when
 killing the server in the cypress preset (#30994)

## Current Behavior

Cypress e2e tasks fail when trying to kill the web server with:

```bash
TypeError: Cannot read properties of undefined (reading 'childProcess')
    at /<repo path>/node_modules/@nx/cypress/plugins/cypress-preset.js:65:30
    ...
```

## Expected Behavior

Cypress e2e tasks should not fail when trying to kill the web server.
