node-runner: add support for 22.04 + build instructions

Description

1. There are no instructions on how to build this repo. Since release only targets amd64 users who are running aarch64 will not know how to install this. Added build instructions.

2. Added build support for Ubuntu 22.04 ( Jammy ).

Looks like a bit more work needs to be done, since even if users build this, radixdlt/keygen:1.3.3 does not support aarch64 either.

Some other docker images missing aarch64 support:

radixdlt/htpasswd
radixdlt/radixdlt-nginx

radixdlt/babylon-nginx

Thanks for the PR. We are supporting Ubuntu 22.04 starting babylon.

I intend to build all images for both amd64 and arm64 for the babylon release. Your list helps me a lot. I had forgotten about the htpasswd image for example.

I am glad that people are looking for efficient ways to run our software and the new arm machines are certainly great machines for that. I will update here and on Discord about the progress of arm support.

All changes related to babylon are happening in a seperate repository:
https://github.com/radixdlt/babylon-nodecli

This helps us seperate major network versions.

Thank you! in any case, are you able to add build instruction in repos so people can build their own images? Similar to something I added in this PR ?
