Currently when a shopfloor operator modifies the operator, operator images are not visible and only place holder images are visible.

## Steps to produce:
- Install Manufacturing with demo data
- Login as Marc Demo
- Open shopfloor

## Observed Behavior:
Operator is unable to see their own profile picture and when you press the Edit Operator the operator is not able to see their as well as other operators images as well.

## Root cause:
This issue occurs because by default an operator's user does not have access right for `Employees` in Human Resources section as they are not an HR officer nor an administrator.

So when the user tries to access the image url that is meant for users with those access rights (HR officer / Administrator) at [1] and at [2].

The system returns a placeholder image instead of the employee image since the operator does not have access to hr employee model but does have access to hr employee public as per this [commit](https://github.com/odoo/odoo/commit/c9ca3761464413327d2beb697553a3ccd7eef4d1)

## Solution:
Allowing operators to see images can be done by modifying the links to use the public model instead of the private model.

This will allow operators see other operators based on images and should improve user experience.
