Jane 7.6.0 relies on Symfony 7.0?

[achton]

Jane version(s) affected: 7.6.0

Description
When I upgraded to 7.6.0 and regenerated my OpenAPI models with Jane, I got this runtime error:

Fatal error: Declaration of MyApplication\api\Normalizer\CaseOwnedNormalizer::supportsDenormalization($data, $type, ?string $format = null, array $context = []): bool 
must be compatible with Symfony\Component\Serializer\Normalizer\DenormalizerInterface::supportsDenormalization($data, $type, $format = null) 
in /var/www/generated/jane/Normalizer/CaseOwnedNormalizer.php on line 524

Due to the CMS framework I use (Drupal), my runtime dependencies are locked at symfony/serializer:^4.4.7. This means that the signature for the supportsDenormalization() method is no longer compatible with the generated normalizers from Jane, hence the fatal error above.

This appears to be the case all the way up to Symfony 6.4.

How to reproduce
I can't share my schema, but I assume any OpenAPI schema that is denormalized using Symfony <7.0 will experience this error.

Possible Solution
I assume this comes from the recently added support for Symfony 7, which also dropped support for older Symfony versions.

However, be aware that both Symfony 5.4 and 6.4 are LTS versions with bugfix support for at least another 18 months. 4.4 was just EOL'ed a couple months ago, so that's my own problem, but you might consider adding CI tests for the other major Symfony versions to avoid regressions.

I also got this error on Symfony 7.
