Fixed #18119 - double formatting for acceptance/decline date

[snipe]

This should fix the error/weird date on checkin acceptance and decline. We were double-Helpering the dates, which already get converted here:

snipe-it/app/Http/Controllers/Account/AcceptanceController.php

Lines 154 to 156 in c301312

	'check_out_date' => Helper::getFormattedDateObject($acceptance->created_at, 'datetime', false),
	'accepted_date' => Helper::getFormattedDateObject(now()->format('Y-m-d H:i:s'), 'datetime', false),
	'declined_date' => Helper::getFormattedDateObject(now()->format('Y-m-d H:i:s'), 'datetime', false),

Fixes #18119
