Code Review
This pull request updates the Go version to 1.25.0 and upgrades numerous module dependencies across the project. Key changes include removing the usage of klog/v2 in cmd/prometheus/main.go and modifying the informerWatchErrorHandler in discovery/kubernetes/kubernetes.go to use context.Background(). A review comment suggests that while context.Background() is acceptable, propagating a more specific context from the Run method would be a more robust solution for cancellation and tracing.

Using context.Background() is acceptable here, but it would be better to use the context from the Run method to allow for proper cancellation and tracing propagation.
This can be achieved by adding a ctx context.Context field to the Discovery struct, setting it in the Run method, and then using it here. This would require careful handling of locks to avoid race conditions or deadlocks.
An alternative approach without changing the struct would be to create a closure for the error handler inside the Run method where the context is available.
Given the current structure, context.Background() is a safe choice, but propagating the context would be a more robust solution.
