Add test to the list of methods that do not get parentheses

[bibstha]

• Ruby version: 2.7.2
• Rubyfmt git sha: 9ed05fc

Input file

test "this is a test in rails" do
  assert(true)
end

Rubyfmt's output

test("this is a test in rails") do
  assert(true)
end

This breaks because

There was an old issue: #54 that mentions a bunch of keywords that shouldn't have () after the method call. However test has not been included in the list in rubyfmt.

test is like describe or it keywords that Rails uses to define test cases and is widely used. Therefore this should be added too.
