Add documentation for network-public-ip plugin

[luftaquila]

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!

649-658: Documentation looks good; consider adding trailing space for style consistency.

The documentation is clear and follows the established plugin pattern. The functionality is correct as-is.

For consistency with other plugin examples in this file (e.g., battery-label at line 205, network-offline-label at line 633), consider adding a trailing space in the example:

-set -g @dracula-network-public-ip-label "󰖟"
+set -g @dracula-network-public-ip-label "󰖟 "

Both approaches work since the script adds a space programmatically; this is purely for documentation style consistency.

28-28: LGTM!

The TOC entry is correctly positioned alphabetically and follows the established format.

scripts/network-public-ip.sh (1)

22-23: LGTM!

The implementation correctly:

• Reads the label option using get_tmux_option with a sensible default of "IP"
• Adds the missing space between the label and IP value in the output
• Follows the established pattern used by other plugins in this repository

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.

[luftaquila]

Oh I didn't know that. I refer to some plugins I'm using such as uptime and cpu-arch and there was space between the label and text, so I added it.

So it should be like this, right?

Suggested change

	echo "$network_public_ip_label $ip" > "${DATAFILE}"
	echo "$network_public_ip_label$ip" > "${DATAFILE}"
