[FIX] website_hr_recruitment: remove useless csrf_token field

Steps to reproduce the bug:
- Go to /@/jobs/apply/experienced-developer-4
- Click on "Edit" button
- Click anywhere in the form
- Try to add a field
=> Nothing happens

Expected behavior:
You should be able to add a field without any problem.

Explanation of the bug:
A dynamic element is in the form (csrf_token) and it is preventing
the form to be modified correctly.
This was an artifact of a mistake made in commit [1].

Behavior after the fix:
You can add a field without any problem.
