Since this method already exists, we are not allowed to change the signature.

Suggested change

	public function postStoreProcess(TableInterface $table, array $newTags = [], bool $replace = true): void
	{
	$this->postStore($table, $newTags, $replace);
	public function postStoreProcess(TableInterface $table, $newTags = [], $replace = true): void
	{
	@trigger_error('7.0 Method postStoreProcess() is deprecated, use postStore() instead.', \E_USER_DEPRECATED);
	$this->postStore($table, (array) $newTags, (bool) $replace);
	}

Also please update the deprecation message with the replacement syntax.
