Toolbar::setFiles() requires int [strict_types=1]

[John-Betong]

Info
I have been trying for over a week to trace a new site's "Network connection Error" from going down overnight. No errors in logs so added "strict_types=1" to all PHP app and system PHP files, also set .env -> CI_ENVIRONMENT = development and eventually managed to get some errors reported.

Describe the bug
Incorrect type being passed to

CodeIgniter 4 version
CI_VERSION - 4.1.1

Affected module(s)
file: ./system/Debug/Toolbar.php
[code]
protected function format(string $data, string $format = 'html'): string
{
$data = json_decode($data, true);

	if ($this->config->maxHistory !== 0)
	{
		$history = new History();
		# PROBLEM - 2021-03-06 - FORCE (int)
		# CRITICAL - 2021-03-07 04:29:00 --> Argument 1 passed to 
		# CodeIgniter\Debug\Toolbar\Collectors\History::setFiles() 
		# must be of the type int, string given, 
		# called in /var/www/ci4-strict.tk/system/Debug/Toolbar.php on line 442
		$history->setFiles(
				(int) Services::request()->getGet('debugbar_time'),
				$this->config->maxHistory
		); 

		$data['collectors'][] = $history->getAsArray();
	}

[/code]

Expected behavior, and steps to reproduce if appropriate
did not expect web page to crash

This is a problem with using strict types, something the framework does not guarantee. If you would like to submit a PR I will review it but I don't consider this one a "bug".
