PHP 8.1 warning on passing null to explode

[hermitpopcorn]

When running on PHP 8.1, hits to API endpoints will emit a warning that says:

explode(): Passing null to parameter #2 ($string) of type string is deprecated in /var/www/html/vendor/apiato/core/Traits /ResponseTrait.php on line 90

originating from this line in parseRequestedIncludes function in ResponseTrait:

core/Traits/ResponseTrait.php

Lines 88 to 91 in cbf2aca

	protected function parseRequestedIncludes(): array
	{
	return explode(',', Request::get('include'));
	}

Due to Request::get('include') returning null and accepting null has been deprecated.

The same thing may happen to the function before it, since there's also a call to Request::get('filter') and then the return value gets exploded in the following line.

Seems easy to fix, such as by adding ?? '' to them, also maybe there are more places where Apiato calls explode on a possibly null/falsy value?

Thank you! I fixed this in Core v8.
