/**
* Generates a unique title by appending an incremented number if a title with the same name already exists in the array.
* This can be useful when you need to ensure unique names (e.g., for file names, database entries, etc.) in a list.
*
* @template T - The type of items in the array, defaults to a generic record.
* @param title - The initial title to check for uniqueness.
* @param arr - The array of objects where the title should be unique.
* @param predicate - The key of the object to check uniqueness against (e.g., the property of the object that stores the title).
* @param splitOperator - The character or string used to split the title and the appended number (defaults to `'-'`).
* @param startFromZero - If `true`, it checks if the title can exist without any appended number and starts counting from 0 (if `false`, it starts from 1).
* @returns A unique title string, with an appended number if necessary.
*
* @example
* const items = [{ name: 'Project' }, { name: 'Project-1' }];
* const uniqueTitle = generateUniqueTitle('Project', items, 'name');
* console.log(uniqueTitle); // 'Project-2'
