Allow users to update the article route name [backend]

**Description**

The functionality should allow changing the article name. This will fix the legacy names used when other users share an article and the article change its name.

**Note**

- Create a history table (post_name_history) with the all articles name saved, to avoid broken links in the future
- If the user updates the article name, the old name is saved in the post_name_history
- When an article is requested by name, we should search it in the list of articles and if it didn't exist, then we should search in the history table
