Cop idea: disallow successive Array#push

[ydakuka]

Actual behavior

I have the following code:

arr = []

arr.push(0)
arr.push(1)
arr.push(2)

# or

arr.push(0).push(1).push(2)

I run rubocop and don't get any offences:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop file.rb 
Inspecting 1 file
.

1 file inspected, no offenses detected

Expected behavior

I expected to receive the code:

arr = []

arr.push(0, 1, 2)

Rubocop

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop -V
1.54.1 (using Parser 3.2.2.3, rubocop-ast 1.29.0, running on ruby 2.7.8) [x86_64-linux]

Even further, it'd be cool if another cop could take that output, and just simplify down to a literal:

-arr = []
+arr = [0, 1, 2]

-arr.push(0, 1, 2)
