Improve organization field in the create issue screen raised through portal

The organizations field in the create issue screen is blank shown as None when we raise a ticket through the portal as a private request

Steps to Reproduce

1. Add an organization to the project
2. Create a ticket using the customer portal
3. Choose the option 'Private Request'
   
4. Observe that the organizations field is blank showing none
   

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available

Suggested Solution

• Display an Organisation field on top of the "Private request" lock icon.
• Rename "Private Request" to "Organization with Private"
