[BUG] get-packages.xq not compatible with exist-db 7.0.0-SNAPSHOT

[line-o]

Describe the bug

The deprecated function response:stream-binary#2 is dropped in exist-db 7.0.0-SNAPSHOT
This leads to the public repo to return a Status code 500 for all package requests if the public repo is installed on an instance of exist-db 7.0.0-SNAPSHOT

Expected behavior

Public-repo to deliver packages on exist-db 7.0.0-SNAPSHOT as well

To Reproduce

Attempt to download a package

curl http://localhost:8080/exist/apps/public-repo/public/test-app.xar
