fix(tests): Round 32 - Fix ServiceMonitor field name

Relabelings field error in servicemonitor_test.go:
- Changed Relabelings to RelabelConfigs
- Prometheus Operator v1.Endpoint uses RelabelConfigs field name
- Field was renamed in newer versions of prometheus-operator
- Fixes unknown field error at line 95

This aligns with the Prometheus Operator API specification
where relabeling configurations are stored in RelabelConfigs.

Errors fixed in Round 32: 1
Total errors fixed across ALL 32 rounds: 142
