[BUG] container image cannot run in restricted environments

[ibotty]

Describe the bug

It would be great to allow the image to run as non-root. Ideally with a random user (as required by OpenShift/OKD). I can prepare a pull that only changes the entrypoint and chowns the env-File.

How can we reproduce the behavior
Run the container image as non-root, e.g. podman run --rm --user 99 taigaio/taiga-events:

./docker/entrypoint.sh: line 15: can't create /taiga-events/.env: Permission denied

Workarounds
Run the image as root.
