Splash screen in v5 seems to be broken

**Describe the bug**
After updating to 5.0.1 the splash screen is nearly blank. But after taking a closer look the splash.png is in the upper left corner, but super tiny.

**To Reproduce**
Steps to reproduce the behavior:

1. update to v5
2. config a splash screen
3. yarn cap open @capacitor-community/electron

**Expected behavior**
Show the spash.png filling the view.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Desktop (please complete the following information):**

- OS: Ubuntu
- Version 23.10

**Additional context**

I guess this change is leading to this behaviour: https://github.com/capacitor-community/electron/blame/f7ce86454469e967b41c1db8f51ddb942d278ca9/src/electron-platform/ElectronSplashScreen.ts#L48

I also played around with the before and after html snippets an ran in the same issue.
