Releasing 3.7.8

I propose to release 3.7.8, with a vulnerability fix.
Do you want to include anything else in this release?

Hi. I don't know at the moment. Thanks for your effort,

There was a problem with the MacOS notarization so I published 3.7.9 in the same go, with a higher timeout for notarization. The corresponding change is here: Bump notarization timeout from 10m to 15m by wetneb · Pull Request #6357 · OpenRefine/OpenRefine · GitHub
