Add comments to wireless access point scripts
Related https://github.com/tiny-pilot/tinypilot/issues/1711
This is a follow-up PR to a review comment asking for more code comments in our enable-wifi-ap and disable-wifi-ap scripts.
@db39 - In https://github.com/tiny-pilot/tinypilot/pull/1778, we've converted your blog post code snippets to standalone scripts, with minor changes. However, I wasn't too sure if I understood what each command was doing.
This PR adds comments to these scripts. Could you double check that the comments make sense or suggest alternatives?
@db39 - Just checking to see if this is still on your radar?
@jdeanwallace - Thanks for the ping on this - it completely fell off my radar. I'll review it today.
