feat: add previous and next button in content.html (#763)

* fix: linkedlist_stack.py 中的peek方法需要判空raise Error

栈空的时候不能再 peek() 。另外由于 pop() 复用了 peek() ，栈空时返回的 None 会传递到 pop() 中的 num ，导致后续的继续执行 
 self.peek.next 报错等后续问题

* Update linkedlist_stack.py

* Update linkedlist_queue.py

* Update linkedlist_deque.py

* feat: Move the pagination nav above the comments

* feat: Move the pagination nav above the comments

* Delete docs/overrides/partials/footer.html

* Update content.html
