I've found out that the documentation for the network-public-ip plugin was missing.

This PR adds the docs of it, and add a missing space between the label and the IP value of it's output.

Thank you!

Walkthrough

This pull request adds documentation for a new network-public-ip option and updates the network-public-ip script to default the label to "IP" and emit the label and ip separated by a space.

Changes

Cohort / File(s)	Summary
Documentation updates docs/CONFIG.md	Added network-public-ip entry under the network group and updated the table of contents; included description and a Nerdfont label example.
Script label retrieval scripts/network-public-ip.sh	Changed label retrieval to read a tmux option into a variable with default "IP" (instead of empty) and output the label and IP separated by a space.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Check scripts/network-public-ip.sh for correct default handling and output formatting (consumer expectations of "label ip" vs previous format).
• Verify docs/CONFIG.md TOC link and example match the implemented output.

Thank you very much for your contribution! I will gladly merge the docs, but the lack of a space is actually intentional, as it is supposed to be up to the users config how much white space there is.
