arm Docker image

[samuel-p]

I would like to run your tiddlywiki-docker image on my Raspberry PI using Docker. Could you please add arm support for your Docker image?

I built a arm docker image from the docker file of this repo. My github actions to build the docker image is here https://github.com/contrun/infra/blob/ab024c82f8b8036c676861b5a4e934e420aaf9b0/.github/workflows/docker-tiddlywiki.yml . Please checkout https://hub.docker.com/r/contrun/tiddlywiki/ to see if this works.
