Feature Request: Add published date on both courses and labs

[Ni-zav]

As the growing industry of technology rapidly changing, I propose to published date be added. in my cases, I tried svelteKit course some weeks ago but I realized after that, that I was using sveltekit 5 in my development rather than the 4. took me abit of time but if there is a techstack that got updated massively, one of these course will surely be impacted.
