Container image is privileged

[almereyda]

When displaying the /boot page of my instance, it says:

System user is sane

It is good practice not to run Grist as the root user.

User appears to be root (UID 0)

❌

It is good practice to provide unprivileged Container images, by using the USER directive. This has implications on the way in which the image is built.
