DoctrineDataCollector::executionTimePercentage calculation triggers deprecation warning in PHP 8.1

[friek]

In Doctrine\Bundle\DoctrineBundle\DataCollector::getGroupedQueries the percentage of execution time of a query is being calculated. For the calculation executionMS is used in the query information and this value appears to be set in Doctrine\DBAL\Logging\DebugStack::stopQuery of doctrine dbal.
The stopQuery function sets a float in executionMS (microtime(true) - $this->start), while DataCollector::executionTimePercentage has its parameters typed with int and this is apparently the cause of the deprecation warning.

Although not a major problem, this is mildly annoying as it gets triggered for every executed query.

Tested with:

• PHP 8.1.0
• Symfony 5.4.1
• doctrine/doctrine-bundle 2.5.2
• doctrine/dbal 3.2.0
