Upgrade to Symfony 6.1

Don't mind much about the `sanitize_html` Twig filter. I added it quickly to make the application work. We're discussing about how adding again this Twig filter in the Symfony HtmlSanitizer component.

These are the remaining deprecations:

```
Remaining indirect deprecation notices (6)

  1x: The "DAMA\DoctrineTestBundle\Doctrine\DBAL\StaticDriver" class implements "Doctrine\DBAL\VersionAwarePlatformDriver" that is deprecated All drivers will have to be aware of the server version in the next major release.
    1x in PHPUnitExtension::executeBeforeFirstTest from DAMA\DoctrineTestBundle\PHPUnit

  1x: The "Symfony\Bridge\Doctrine\Logger\DbalLogger" class implements "Doctrine\DBAL\Logging\SQLLogger" that is deprecated Use {`@see` \Doctrine\DBAL\Logging\Middleware} or implement {`@see` \Doctrine\DBAL\Driver\Middleware} instead.
    1x in AddUserCommandTest::testCreateUserNonInteractive from App\Tests\Command

  1x: Method "ArrayAccess::offsetExists()" might add "bool" as a native return type declaration in the future. Do the same in implementation "Dflydev\DotAccessData\Data" now to avoid errors or add an explicit `@return` annotation to suppress this message.
    1x in BlogControllerTest::testAdminShowPost from App\Tests\Controller\Admin

  1x: Method "ArrayAccess::offsetGet()" might add "mixed" as a native return type declaration in the future. Do the same in implementation "Dflydev\DotAccessData\Data" now to avoid errors or add an explicit `@return` annotation to suppress this message.
