Current Behavior

We're testing v0.42.2 having upgraded from v0.37.0, and we're now receiving the following warning:

[WARNING] (com.google.cloud.spanner.SpannerCloudMonitoringExporter exportSpannerClientMetrics): Metric data has missing instanceId. Skipping export.

We haven't made any changes to our PGAdapter setup aside from bumping versions.

Context (Environment)

• Running PGAdapter 0.42.2 as a sidecar in GKE
• PGAdapter configured with 1 vCPU and 2GB Memory limits (actual CPU use hovers at ~ 100mCPU)
• PGAdapter executed with the following args:

- args:
  - -p
  - <REDACTED>
  - -i
  - <REDACTED>
  - -d
  - <REDACTED>
  - -enable_otel
  - -otel_trace_ratio=0.05

Environment Variables:
JDK_JAVA_OPTIONS = "-Xmx1600M -Xms1600M -XshowSettings:vm" 

Looks like v0.42.2 is using libraries-bom 26.52.0, which uses google-cloud-spanner 6.83.0 and we're hitting this check that was introduced in 6.81.1.
