ibexa/post-install affected by Breach with Varnish VCL
### Impact
This is not a vulnerability in the code per se, but included platform.sh Varnish VCL templates and Apache/Nginx vhost templates enable compression of API and JSON messages. This is a potential case of the BREACH vulnerability, which affects HTTP compression, where secrets can be extracted through carefully crafted requests. The fix disables compression in these templates. Please make sure to make the same change in your configuration files, see the release notes for specific instructions.

The default configuration for platform.sh (.platform.app.yaml) allows access to uploaded files if you know or can guess their location, regardless of whether roles grant content read access to the content containing those files. If you're using Legacy Bridge, the default configuration also allows access to certain legacy files that should not be readable, including the legacy var directory and extension directories.
