Upgrade to Symfony 5.3

For now, it's Symfony 5.3 RC1, but we'll keep updating this branch until 5.3 stable.

-----

Things that I found while upgrading:

### Missing UPGRADE guide entry?

In the UPGRADE guide (https://github.com/symfony/symfony/blob/5.3/UPGRADE-5.3.md) we don't even mention `enable_csrf`, but this change is needed in `config/packages/security.yaml`:

Replace this:

```yaml
form_login:
    csrf_token_generator: security.csrf.token_manager
```

by this:

```yaml
form_login:
    enable_csrf: true
```

-----

### Unexpected failures

The upgrade guide mentions this:

```
PropertyInfo:

Deprecated the Type::getCollectionKeyType() and Type::getCollectionValueType() methods,
use Type::getCollectionKeyTypes() and Type::getCollectionValueTypes() instead
```

But we have these test failures:

```

App\Tests\Controller\Admin\BlogControllerTest::testAdminNewPost
Error: Call to undefined method Symfony\Component\PropertyInfo\Type::getCollectionValueTypes()

### Unexpected direct deprecations

I see the following "direct deprecation" notices, but I don't know how they can be "direct deprecations". We don't use any of these in our code:

```
Remaining direct deprecation notices (7)
