Continue lesson

[Zerotask]

Add an option to continue your option.
This is now prepared. The lesson component will save:

• title
• url
• date

the next time a user will open a non-lesson page, there should be a pop-up / notification if he / she wants to continue the lesson.
https://sweetalert2.github.io/ could be a possible package to use that.

This message should just come 1 time and then it should be deleted from the local storage and this popup should only come after a certain amount of time have passed.
