chore: enable parallel run for override in 202405 (#16227)

Description of PR
Enable parallel run for override_config_table/test_override_config_table_masic.py in 202405

Summary:
Fixes # (issue) Microsoft ADO 30056122

Approach
What is the motivation for this PR?
Previously we disabled parallel run for override_config_table/test_override_config_table_masic.py in 202405 as it's not compatible with the existing infra. Now this test has been enhanced in #16226 so we can enable parallel run for it.
