If I modify some libsonnet file, what should I do when I upgrade.

[hwdef]

for example, if I modify kube-prometheus/jsonnet/kube-prometheus/prometheus-adapter/prometheus-adapter.libsonnet according to my needs.Later, I want to follow the upstream to upgrade to the new version of kube-prometheus, what should I do?

You shouldn't modify this file since kube-prometheus is meant to be used as a library. More in https://github.com/prometheus-operator/kube-prometheus#customizing-kube-prometheus
