After a deep-dive into the weathergov.js weather provider script, I believe the documentation needs to be updated...

https://docs.magicmirror.builders/modules/weather.html#configuration-options

Under "Weather.gov options"

• apiBase "Possible value" should be 'https://api.weather.gov' as "/points/" is appended in the weathergov.js code.
• weathergov.js no longer uses the weatherEndpoint configuration setting as the docs suggest. This option should be deleted from the documentation.
