chore: public_address for TCP node has higher priority from env/config (

tari-project#3600)

Description
---
The tcp `public_address` read from env/config (if set) instead of `base_node_id.json`.
I've added a comment to the newly generated `base_node_id.json` that this value is overwritten.
I've chosen json5 so it's backwards compatible.

How Has This Been Tested?
---
Manually.
