feat: add support for displaying the P2P Address for node secrets info

[zivkovicmilos]

Description

Closes #1922

This PR introduces a new section to the Node P2P Info secrets output, that displays the P2P connection address.
The secrets fetch command remains unchanged, and this info can be displayed by calling gnoland secrets get NodeKey

It displays the following values:

• if the config is not initialized yet, the default p2p listen address is used
• if the config is initialized, the p2p listen address value is used

These values will be easily fetch-able when we introduce json output support for these outputs in #2301

Thank you @zivkovicmilos to bring this in. It certainly improves the bootstrap experience.

One small feedback. WOuld it make sense to call the command NodeId rather than NodeKey. What is the rationale behind the choice of word NodeKey?

I don't think printing protocol (tcp://) is necessary.
Other than that LGTM 👍

@r3v4s
Thank you for the heads up about the protocol part of the P2P address 🙏

I've resolved it in:

@mazzy89

I've updated it to NodeID, since we display more information now 👍

Thank you for the suggestion 🙏
