Style/For correction breaks when using array concatenation

[JasonBarnabe]

a = [1]
b = [2]
c = [3]

for n in a + b + c
  puts n
end

Outputs:

1
2
3

Running rubocop -A on this method:

style_for_test.rb:5:1: C: [Corrected] Style/For: Prefer each over for.
for n in a + b + c ...
^^^^^^^^^^^^^^^^^^

File becomes:

a = [1]
b = [2]
c = [3]

a + b + c.each do |n|
  puts n
end

Outputs:

3

Output has changed!

Expected correction:

a = [1]
b = [2]
c = [3]

(a + b + c).each do |n|
  puts n
end

Which retains the original output.

rubocop -V:

1.29.1 (using Parser 3.1.2.0, rubocop-ast 1.18.0, running on ruby 2.7.6 x86_64-linux)

I'll attempt to fix this.
