feat(#736): Switch tabs with keyboard shortcut (#812)

* feat(#736): Switch tabs with keyboard shortcut

1. Registered keyboard events in Hotkeys/index.js
2. Added logic for replacing `state.activeTabUid` to switch active tab as per keyboard event.
3. Maintained a stack `recentUsedTabsStack` for tab visit history and pop out on `Ctrl+Tab` keyboard event.

* feat(#736): Switch tabs with keyboard shortcut

Keeping this feature request only limited to CTRL+PGUP and CTRL_PGDN button clicks functionality. Hence removing logic for CTRL+TAB click functionality.

* feat(#736): Switch tabs with keyboard shortcut

clean up

* feate(#827): Switch tabs with keyboard shortcut

* Implimented logic of cyclic traversal of tabs array with % opreator.
