Description

Goal

The goal of this PR is to add the last feature of multilingual support which are adding a new content and deleting multilingual contents.

Changes

The following changes have made on the backend:

• Updated thecreate endpointto only add new contents with the create content endpoint. Language versions will be added using the edit endpoint
• Updated the edit endpoint to create Language versions of contents.
• Updated delete endpoint to delete language version when a language_id is provided and delete the whole content otherwise.
  The following changes have been made on the backend:
• Added a new content using the New button
• Added a delete button on the edit page and the Content Modal to delete language versions of contents. If the last language version is deleted, the user is redirected to the content landing page.
• Updated the back arrow to redirect to the content landing page.
• Updated the add page to redirect to edit instead of the landing page when a new content is added/edited.

Future Tasks (optional)

With this PR, all features are implemented. The future tasks will be:

• Add backend tests
• Clean up (if necessary)

How has this been tested?

This is the last multilingual feature PR, so all multilingual features have been tested:

• Adding a Content
• Adding a language version of the content (both from landing and Modal)
• Viewing different language versions of contents
• Updating a content
• Deleting a content
• Deleting a Language version of a content
  I suggest testing all this extensively while reviewing to make sure there is no additional changes to make to the backend.

Hello @lickem22 , thank you so much for this!! It's looking great.. though we should rethink language related UI/UX. Perhaps something we can get outside help on :-)

I am requesting just 1 change, other ones please address/create tickets as you see fit. Let me know what you think.
