This commit modifies the modal for editing bot information to
use edit_fields_modal framework.
We also change the id of form element of this modal such that
it makes sense with the actual use of modal and there is no
problem with this change as styling of this modal is not
affected.
Moved `admin_bot_form` template to `/templates/settings/` folder as
earlier, it was inaccurately placed within the `/templates` folder
and `settings` folder is specifically for storing administrative
UI templates.
