Steps to reproduce the problem

The issue occurs with the second 1.times loop in the following class:

require 'forwardable'

class Buffer
  extend Forwardable

  def_delegators :@data, :[], :[]=, :slice

  def self.alloc(length)
    Buffer.new(length)
  end

  def initialize(length)
    @data = Array.new(length, 0x00)
  end

  def read_uint8(offset = 0)
    result = 0
    1.times do |i|
      result <<= 8
      result += @data[offset + i]
    end

    result
  end

  def write_uint8(value, offset = 0)
    1.times.reverse_each do |i|
      @data[offset + i] = value & 0xff
      value >>= 8
    end
  end

  def read_uint16_be(offset = 0)
    result = 0
    2.times do |i|
      result <<= 8
      result += @data[offset + i]
    end

    result
  end

  def write_uint16_be(value, offset = 0)
    2.times.reverse_each do |i|
      @data[offset + i] = value & 0xff
      value >>= 8
    end
  end

  def read_uint32_be(offset = 0)
    result = 0
    4.times do |i|
      result <<= 8
      result += @data[offset + i]
    end

    result
  end

  def write_uint32_be(value, offset = 0)
    4.times.reverse_each do |i|
      @data[offset + i] = value & 0xff
      value >>= 8
    end
  end
end

I note that the first invocation is warned about appropriately:

buffer.rb:18:5: W: [Correctable] Lint/UselessTimes: Useless call to 1.times detected.
    1.times do |i| ...
    ^^^^^^^^^^^^^^

so I'm guessing it may have something to do with the use of reverse_each (in 1.times.reverse_each)

Fixes rubocop#10415.

This PR fixes an error for `Lint/UselessTimes` when using `1.times` with method chain.

This bug fix case does not support auto-correction because it is complicated to cover
the usage of the methods of `Enumerable` returned by `Integer#times` method.

Nice one!

I seem to be the only one around using 1.times in my code, so at least the cop is working in dissuading others 😂
