[Issue] Update `indexer:reset` to call `$indexer->invalidate()`

[m2-assistant]

This issue is automatically created based on existing pull request: #34582: Update indexer:reset to call $indexer->invalidate()

---

I was recently debugging something that was invalidating the indexers.

I added some logging using a before plugin on the invalidate function

public function beforeInvalidate(\Magento\Framework\Indexer\IndexerInterface $subject)
{
    $this->logger->info(
        "Invalidating index",
        [
            'indexer_id' => $subject->getId(),
            'trace' => str_replace(PHP_EOL, '|', (new \Exception())->getTraceAsString())
        ]
    );
}

But this use case isn't caught in my logs.

It seems to me that this command should just call the function that invalidates the indexer rather than repeating the work itself. I'm sorting out my own logging / debugging internally, but this seems sensible to fix here.

magento2/app/code/Magento/Indexer/Model/Indexer.php

Lines 345 to 355 in 227cf92

	/**
	* Set indexer invalid
	*
	* @return void
	*/
	public function invalidate()
	{
	$state = $this->getState();
	$state->setStatus(StateInterface::STATUS_INVALID);
	$state->save();
	}

Manual testing scenarios (*)

1. Call indexer:reset and see the indexer was invalidated
