bug: Security gap in approval workflow allows creator of the task to self-approve

[mgorsk1]

Affected module
UI

Describe the bug
When creating a task (like request description) you can assign either user or a team/group/business unit to approve/decline it. The bug allows for a user to assign a team they are a part of to a task and subsequently self-approve it. It allows to bypass 4 eyes principle I think should be enforced in every scenario for task workflow.

To Reproduce

• add user X to team Y
• create a task 'request description' to a table and add Y team as approvers for this task
• user X can now self-approve the request

Expected behavior

• users can't self-approve if the request was assigned to users team. this enforces 4 eyes principle in every scenario.

Version:

• OS: [e.g. iOS]
• Python version:
• OpenMetadata version: [e.g. 0.8]
• OpenMetadata Ingestion package version: [e.g. openmetadata-ingestion[docker]==XYZ]
