Fix incorrect revive defer rule arguments format in docs

The current documentation lists the defer rule configuration for revive as follows:

- name: defer
  severity: warning
  disabled: false
  exclude: [""]
  arguments:
    - "call-chain"
    - "loop"
    - "method-call"
    - "recover"
    - "immediate-recover"
    - "return"

However, this format is incorrect. According to the official revive rule descriptions (source), the arguments field should be passed as a nested list:

- name: defer
  severity: warning
  disabled: false
  exclude: [""]
  arguments: [["call-chain", "loop", "method-call", "recover", "return"]]

Why is a nested list required?

In revive, the Configure method for the defer rule expects its first argument to be castable to a []any. Since the top-level arguments are passed as a []interface{}, the actual list must be nested as the first element. Otherwise, the cast fails at runtime.

In contrast, rules like early-return handle scalar arguments and use a simple switch structure. But the defer rule iterates over a list of options using range, making the nested structure essential for flexibility and correctness.

This commit updates the golangci-lint documentation to reflect the correct format.
