Quarantine flaky ForceRestartBuildsMetadataMigrationsForSelfManaged spec

Narendranrequested to merge
quarantine-metadata-migration-spec into master

The spec fails in CI because the migration iterates over real database partitions of p_ci_builds, but the CI test database does not have the expected partitions (ci_builds_100/ci_builds_101).

Quarantining while the fix is investigated.
