chore: Fix user permissions

[Eric-Warehime]

Setting a new user in this way ends up with issues when using an entrypoint command since no entries exist in the corresponding etc/ files.

I tried setting the nobody user which is built into distroless images, but then mounting files in to use as a config becomes an issue. It seems pretty low stakes to give users root inside the distroless container, so I'm just reverting for now.
