Remove the additional explicit wait "hack" in progress bar

[cardil]

The additional explicit wait "hack" in the progress bar should be removed. If your UI has a lot of progress bars, this wait will be visible.

client-pkg/pkg/output/tui/progress.go

Lines 188 to 193 in cf1573f

	func (b *BubbleProgress) quitSignal() tea.Cmd {
	// The final pause is to give the progress bar a chance to finish its
	// animation before quitting. Otherwise, it ends abruptly, and the user
	// might not see the progress bar at 100%.
	return tea.Sequence(b.finalPause(), tea.Quit)
	}

But, I don't see a way, with the current API of bubbles' progress, to achieve it otherwise...

Without the wait, we get UI with progress bars that are never 100% completed. See example: #162 (comment)

I don't think it is possible with the current API. When the tea.Quit command is handled, the Bubbletea's renderer stops, and restores the terminal to standard output mode. So, you can't replace the line that was already written.

I think the Bubbletea should allow defining the last tea.Quit state, that will be printed just before the exit, and without waiting for the animation loop to draw it.
