Feat: Added one panel switch per scroll setting

[ImTheSquid]

Added an option in settings to only allow for one panel switch when using the horizontal scroll to switch feature, similar to how Arc works. I added the base English translation for the text.

Thanks. I think it would be better if we moved your debouncing algorithm to Sidebar.switchPanel to avoid double debouncing. Plus, there is already a setting for configuring specific delay time navSwitchPanelsDelay (50ms on my hardware was not enough).

Something like that (in sidebar.actions.ts):

function startPanelSwitchingDebounceTimer(delay: number) {
  switchPanelPause = setTimeout(() => {
    clearTimeout(switchPanelPause)
    switchPanelPause = undefined
  }, delay)
}

let switchPanelPause: number | undefined
export function switchPanel(
  dir: 1 | -1,
  ignoreHidden?: boolean,
  withoutTabCreation?: boolean,
  restartDebouncer?: boolean
): void {
  // Debounce switching
  const delay = Settings.state.navSwitchPanelsDelay ?? 128
  if (switchPanelPause) {
    if (restartDebouncer) { // + check switched scroll direction
      clearTimeout(switchPanelPause)
      startPanelSwitchingDebounceTimer(delay)
    }
    return
  }
  if (delay > 0) startPanelSwitchingDebounceTimer(delay)

//...

And that (in sidebar.vue):

  if (e.deltaX > 0) return Sidebar.switchPanel(1, true, false, Settings.state.onePanelSwitchPerScroll)
  if (e.deltaX < 0) return Sidebar.switchPanel(-1, true, false, Settings.state.onePanelSwitchPerScroll)

Makes sense, I'll switch it over.
