`panic: Only 4K page size is supported on arm64!` when running on a Raspberry Pi 5

[Zeromusta]

Similar to #19, I was attempting to get grist-omnibus up and running, this time on a Raspberry Pi 5 via:

mkdir /tmp/grist-test/
sudo docker run   -p 9999:80   -e URL=http://{hostname-here}:9999   -e TEAM=cool-beans   -e EMAIL=owner@example.com   -e PASSWORD=topsecret   -v /tmp/grist-test:/persist   --name grist --rm   -it gristlabs/grist-omnibus

The container won't start at all:

pi@rpi-base:~ $ sudo docker run   -p 9999:80   -e URL=http://rpi-base:9999   -e TEAM=cool-beans   -e EMAIL=owner@example.com   -e PASSWORD=topsecret   -v /tmp/grist-test:/persist   --name grist --rm   -it gristlabs/grist-omnibus
