Version 4.15 delayed due to regression

[nebulon]

The new weblate 4.15 version failed in our tests so package release is delayed. Upstream issue to track is at https://github.com/WeblateOrg/weblate/issues/8510

To update here, this was not an upstream regression, but a missing postgres extension which was not available on Cloudron, the next Cloudron version will have that then.

Package release is made and will be available only for Cloudron 7.4
