bug: long comments format inserts unwanted extra lines infintely

Bug Report

Cairo version:
scarb 2.6.4+nightly-2024-06-26 -> cairo: 2.6.4 (78777e38e) 78777e3

Consider the following code, with a long link as a comment:

// my comment has a link is very long https://github.com/aurora-is-near/aurora-engine/blob/1213f2c7c035aa523601fced8f75bef61b4728ab/engine-modexp/src
fn foo(){

}

running scarb fmt will turn it into

// my comment  has a link that is very long
// 
// https://github.com/aurora-is-near/aurora-engine/blob/1213f2c7c035aa523601fced8f75bef61b4728ab/engine-modexp/src
fn foo() {}

running again:

// my comment has a link that is very long
//
//
//
// https://github.com/aurora-is-near/aurora-engine/blob/1213f2c7c035aa523601fced8f75bef61b4728ab/engine-modexp/src
fn foo() {}

-> if the width of a comment line is bigger than a defined threshold, the formatter will attempt to split it and add empty new lines infinitely.
