* Prompts the user to select multiple choices from a list of choices, if the input is invalid, it will prompt the user again for a valid input
*
* @param {string} prompt The prompt to display to the user
* @param {string[]} choices The choices to display to the user
* @param {PromptMultipleChoiceOptions} options The options for the prompt
*
* @returns {Promise<string[]>} The validated choices the user selected
*
* @example
* ```typescript
* // Prompt the user to select a choice
* const choices = await promptMultipleChoice('Select a choice', ['A', 'B', 'C']);
* console.log(choices);
*
* // Prompt the user to select multiple choices with a default selection
* const choices = await promptMultipleChoice('Select a choice', ['A', 'B', 'C'], {
* defaultSelected: ['A', 'B'],
* validator: (input) => input.length > 0,
* validationErrorMessage: 'You must select at least one choice',
* });
* console.log(choices);
*
* // Prompt the user to select a choice using a custom theme
* const choices = await promptMultipleChoice('Select a choice', ['A', 'B', 'C'], {
* theme: new EasyCLITheme(),
* promptTheme: 'info',
* });
* console.log(choices);

* // Prompt the user to select a choice using a custom displaying the choices with a theme
