featureFlags.EnableTektonOCIBundles becomes unknown fields

Pipeline Version: v0.62.4

unable to delete a pipelinerun with EnableTektonOCIBundles flag, getting below error even while removing finalizer

error: pipelineruns.tekton.dev "installer-l0v75d" could not be patched: admission webhook "webhook.pipeline.tekton.dev" denied the request: mutation failed: cannot decode incoming new object: json: unknown field "EnableTektonOCIBundles"

For some reason, EnableTektonOCIBundles added into pipelinerun status.provenance.featureFlags, EnableTektonOCIBundles - completely removed on 0.62.x [1] so it becomes unknown field. The Pipelinerun resources were already marked for deletion, and we can not change the resource, other than removing the finalizers. But here the pipeline webhook 0.62.x doesn't like unknown field EnableTektonOCIBundles and rejecting. It is a kind of dead lock now.
