Up-to-date docker image in dockerhub

[pluja]

I'm maintaining an up-to-date docker hub strfry image for anyone to pull and use, I have set up a GitHub action that checks for updates every day and pushes the update if needed:

https://hub.docker.com/r/pluja/strfry

The tags available are latest and the version number, i.e: 0.9.6.

Feel free to close this issue, it's just an informative issue to let the stfry community know about it.
