feat: add support for dbal 4

#298

Maybe the only problem is this change.
https://github.com/doctrine/dbal/blob/4.0.x/UPGRADE.md#bc-break-renamed-sqlite-platform-classes

TODO: I know there must be a bc layer for dbal < 4

Solving #300 would help development.

On the 3.x branch, with doctrine/dbal 4, this line is not working:

LiipTestFixturesBundle/src/Services/DatabaseToolCollection.php

Line 52 in 696c0e0

$databaseTool = $this->items[$registry->getName()][$driverName] ?? $this->items[$registry->getName()]['default'];

$this->items[$registry->getName()][$driverName] is evaluated as false, null or whatever and it switch to the statement after ??.

Update: you found the issue: DatabaseToolCollection registers an item with key Doctrine\DBAL\Platforms\SqlitePlatform then later the key Doctrine\DBAL\Platforms\SQLitePlatform is searched.

Please check this:

• [3.x] feat: support doctrine/dbal 4 #306

Feel free to backport it to the 2.x branch.

Tests were OK on local environment but not on CI, because the versions of databases used on GitHub Actions were outdated: bf29b7d

Suggested change

	} elseif ($platform instanceof SQLitePlatform) {
	} elseif ($platform instanceof SqlitePlatform || $platform instanceof SQLitePlatform) {

Is this needed to keep compatibility?

[alexislefebvre]

Suggested change

	return $this->connection->getDatabasePlatform() instanceof SQLitePlatform;
	return $this->connection->getDatabasePlatform() instanceof SqlitePlatform || $this->connection->getDatabasePlatform() instanceof SQLitePlatform;
