Status lights don't match documentation

[makermelissa]

According to https://learn.adafruit.com/adafruit-pyportal/pyportal-hardware-faq#faq-3023990, the lights should act as follows:

Red = not connected to WiFi
Blue = connected to WiFi
Yellow = fetching data
Blue = got data
Cyan = file opening

The status colors are changeable at: https://github.com/adafruit/Adafruit_CircuitPython_PortalBase/blob/main/adafruit_portalbase/network.py#L59-L65

I see several issues here:

1. STATUS_CONNECTED is never used.
2. It looks like the get_strftime() function in network is not setting the status colors.
3. It appears the connected color is currently set to green.
4. It appears the Got Data is blue, though the original comments from the PyPortal library suggest it should have been green (https://github.com/adafruit/Adafruit_CircuitPython_PortalBase/blob/main/adafruit_portalbase/network.py#L281).
5. The value for STATUS_FETCHING suggests more of an orange color rather than yellow.

I changed docs to show Green for Got Data as well as code, which I believe was the correct color.
