Deleting segment overrides is enforced by "Manage segments" permission in the frontend

[rolodato]

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

See reproduction steps.

Steps To Reproduce

1. Grant a user permissions to manage segment overrides in one environment, but not manage segments at the project level
2. Try to edit an already-created segment override in this environment

Result: segment overrides can be created and edited, but not deleted. The tooltip is incorrect as "Manage segment overrides" does grant permission to delete existing overrides.

Expected behavior

Don't require "manage segments" permission to delete existing segment overrides.
