docs: refine API docs for files in JSUtils dir

[devvaannsh]

In file ScopeManager.js, the parameter definition has been updated like this:

<---- Removed ----> * @param {from: {line:number, ch: number}, to: {line:number, ch: number}}

<---- Added ----> * @param {{line:number, ch: number}} changeList {from: {line:number, ch: number}, to: {line:number, ch:number}}

This change was made because Docusaurus is unable to parse nested objects as parameter types.
