Early feedback: try this

Suggested change
{{< feature-state for_k8s_version="v1.36" state="stable" >}}
{{< feature-state feature_gate_name="KubeletPSI" >}}

and then look for instances of KubeletPSI anywhere in the English docs that might need an update.

For other localizations, each localization team - usually 100% volunteers - picks its own way of working.

/lgtm

[Pressure Stall Information](https://docs.kernel.org/accounting/psi.html)
(PSI) for CPU, memory, and I/O usage. The information is collected at node, pod and container level.
This feature is enabled by default by setting the `KubeletPSI` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/).
Starting with Kubernetes v.1.36, the `KubeletPSI` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) is locked to true and cannot be disabled.
