os-deferred-delete restore server API policy is allowed for everyone even policy defaults is admin_or_owner

[Ghanshyam Mann]

os-deferred-delete restore server API policy is default to admin_or_owner[1] but API is allowed for everyone.

We can see the test trying with other project context can access the API
- https://review.opendev.org/#/c/707455/

This is because API does not pass the server project_id in policy target

and if no target is passed then, policy.py add the default targets which is nothing but context.project_id (allow for everyone try to access)

    Fix os-os-deferred-delete policy to be admin_or_owner

    os-deferred-delete restore server API policy is default to admin_or_owner[1] but API
    is allowed for everyone.

    We can see the test trying with other project context can access the API
    - https://review.opendev.org/#/c/707455/

    This is because API does not pass the server project_id in policy target[2]
    and if no target is passed then, policy.py add the default targets which is
    nothing but context.project_id (allow for everyone who try to access)[3]

    This commit fix this policy by passing the server's project_id in policy
    target.

    Closes-bug: #1863009
