Describe the bug

Placeholder text on an entry field uses the TextStyle of the entry field itself, although it seems to be applied only once clicked upon.

How to reproduce

Click on the entry field.

Screenshots

Example code

func main() {
	application := app.New()
	window := application.NewWindow("Test")

	entryField := widget.NewEntry()
	entryField.PlaceHolder = "Test"
	entryField.TextStyle = fyne.TextStyle{Bold: true}

	window.SetContent(entryField)
	window.ShowAndRun()
}

Fyne version

Go compiler version

1.20.5

Operating system and version

Arch Linux (kernel 6.1.37 LTS)

Additional Information

I would expect it to be bold without having to be clicked on, and in fact I'd even prefer if there were separate styling options for both the placeholder and the text itself, although that's perhaps a feature request =b
