Description

The documentation for mutation policies with json6902 patches includes a small warning that these are not supported for autogen rules for Pods. However the autogen documentation page does not mention this, which led to some confusion as it seemed like it should be a supported use-case.

https://kyverno.io/docs/writing-policies/mutate/#rfc-6902-jsonpatch <--- notes the json6902 exclusion
https://kyverno.io/docs/writing-policies/autogen/ <--- does not note the json6902 exclusion

Recommend adding some similar warning text to docs/writing-policies/autogen/ that autogen is not enabled for patchesJson6902 mutation rules.

Additionally the text at https://kyverno.io/docs/writing-policies/mutate/#rfc-6902-jsonpatch has a somewhat confusing statement mutations using patchesJson6902 to Pods directly is not supported - since you can mutate pods directly with the json6902 patch, you just cannot get the autogen rules that also mutate pod templates in Controller resources.
