v0.15.2 fails to start on read-only RTL-Config.json

[cvx35isl]

Describe the bug

I run the docker image with Kubernetes and have RTL-Config.json punched in from a ConfigMap - this makes it always read-only. Here is how a startup attempt looks then:

To Reproduce
Steps to reproduce the behavior:

1. take v0.15.2 from somewhere, ie. the docker image
2. make RTL-Config.json read-only one way or the other
3. observe it not to start

Your environment

• Version of RTL v0.15.2 and 0.15.1 presumably, last working one is 0.15.0
• using docker image: https://hub.docker.com/layers/shahanafarooqui/rtl/v0.15.2/images/sha256-27fdcc9aa8b156b79073a8017ed4dd059e052784a3d8cf65f21c524c3e1e40b2?context=explore
• given its Kubernetes, I can actually confirm Avoid magic edits of the config #1327
