Users with permissions to manage segments and segment overrides cannot create segment overrides from the Segment

[matthewelwell]

How are you running Flagsmith

• Self Hosted with Docker
• Self Hosted with Kubernetes
• SaaS at flagsmith.com
• Some other way (add details in description below)

Describe the bug

Users with the project-level permission MANAGE_SEGMENTS and the environment-level permission MANAGE_SEGMENT_OVERRIDES should be able to add, and modify segment overrides when viewing the 'Features' tab from a segment. Currently they cannot do so.

Steps To Reproduce

1. Log into the Flagsmith dashboard as a user with permission to manage segments and segment overrides
2. Navigate to any segment, and click on the 'Features' tab
3. Notice that the option to create a segment override does not exist

Expected behavior

The option to create a segment override does exist
