FolderOpenDialog SetOpenText and SetDismissText are ineffective

[BabySid]

Describe the bug:

As the title describes, when i use a folderopendialog, i cannot found any method that set the text of the OPEN button.
And, I call SetDismissText, but it does't have any effect.

To Reproduce:

Steps to reproduce the behaviour:

• Run the code below

Screenshots:

Example code:

func main() {
        myApp := app.NewWithID("go-fyne")

	myWindow := myApp.NewWindow("Widget")
	btn := widget.NewButton("Go", func() {
		fo := dialog.NewFolderOpen(func(uri fyne.ListableURI, err error) {
			if uri != nil {
				fmt.Println(uri.Path())
			}
		}, myWindow)
		fo.SetDismissText("Exit")
		fo.Show()
	})

	content := container.NewVBox(
		widget.NewEntry(),
	)

	myWindow.Resize(fyne.NewSize(800, 600))
	myWindow.SetContent(container.NewBorder(btn, nil, nil, nil, content))
	myWindow.CenterOnScreen()
	myWindow.ShowAndRun()
}

Thanks for this.
We can resolve the SetDismissText not functioning in the next point release, but adding the setting of save text will have to wait a little longer as we don't add API (which this requires) in bug-fix releases.
I will open a PR with SetConfirmText as this matches other dialogs, and works for save/open equally.

The SetDismissText oversight is fixed pending v2.1.4

The bug fix is released, the new API for SetConfirmText will be in v2.2.0
