Looked up using a captive portal and so many other wifi managers.

Decided to just use a push button and display a simple HTML page pulling the details from EEPROM, and replacing text in a template HTML string.  Saving posts the data to EEPROM and reboots it.

I created the webserver on start.  Learned how to serve up HTML files from SPIFFS.

Used Visual Studio code to create the HTML file, with the images using the Miligram CSS file along with Zepto.js.
