nano is not a valid timeEncoding configuration for operator and webhooks

[DaazKu]

The README state that we can use nano as a valid time encoding for:

• operator ->

  charts/keda/README.md

  Line 119 in bb6c9af

  | `logging.operator.timeEncoding` | string | `"rfc3339"` | Logging time encoding for KEDA Operator. allowed values are `epoch`, `millis`, `nano`, `iso8601`, `rfc3339` or `rfc3339nano` |

• webhook ->

  charts/keda/README.md

  Line 258 in bb6c9af

  | `logging.webhooks.timeEncoding` | string | `"rfc3339"` | Logging time encoding for KEDA Operator. allowed values are `epoch`, `millis`, `nano`, `iso8601`, `rfc3339` or `rfc3339nano` |

  (note that it says operator. C/P issue)

Trying to do so results in the following error:

2023-11-27T16:32:51.521594883Z invalid argument "nano" for "--zap-time-encoding" flag: invalid time-encoding value "nano"

Steps to Reproduce the Problem

Use the following to configure the chart:

logging:
  operator:
    level: error
    format: json
    timeEncoding: nano
  metricServer:
    level: 0
    stderrthreshold: ERROR
  webhooks:
    level: error
    format: json
    timeEncoding: nano
