A code fix for fixing inappropriate tuple usages

[psfinaki]

Inspired by this: #11234

Basically suggest changing this code

let g a b = "hello"

let f a b : string =
     g a, b

or this code

let g a b = "hello"

let f a b : string =
     g (a, b)

to this

let g a b = "hello"

let f a b : string =
     g a b
