Support for Nextcloud 33

[badger12345]

Hi,

thanks for this useful app.

I am using Nextcloud 33 and noticed that nextcloud-roundcube is currently not available as NC33-compatible.

Could you please clarify whether support for Nextcloud 33 is planned?

If the app is already working in practice and only the compatibility constraint still needs to be updated, an NC33-compatible release would be greatly appreciated. If code changes are still required, it would also help to know whether the project is actively moving toward NC33 support.

I would be happy to test the app on a self-hosted NC33 instance and report back.

Thanks in advance.
