[binbinlv]

• I have searched the existing issues

Environment

- Deployment mode(standalone or cluster):both
- MQ type(rocksmq, pulsar or kafka):    all
- SDK version(e.g. pymilvus v2.0.0rc2): 2.5.0rc126

Current Behavior

The object name is * rather than the collection names returned by "list_grants()" when grant the role with the built-in privilege group to collection level

role.grant(object="Global", object_name="binbin", privilege="CollectionReadOnly")

>>> role.list_grants()
GrantInfo groups:
- GrantItem: <object:Global>, <object_name:*>, <db_name:default>, <role_name:binbin_new>, <grantor_name:root>, <privilege:CollectionReadOnly>

Expected Behavior

The object name is the collection names rather than "*" returned by "list_grants()" when grant the role with the built-in privilege group to collection level

Steps To Reproduce

from pymilvus import Role
from pymilvus import connections
connections.connect()
role = Role("newRole")
role.create()
role.grant(object="Global", object_name="binbin", privilege="CollectionReadOnly")
role.list_grants()
