NEWS: move to a single weekly news post to reduce noise + only report changes to lectures and major software (QuantEcon.py, mystmd etc.)

I think we should only report major updates on our quantecon website such as changes to lectures (and remove website updates)

the stream of posts isn't particularly interesting until you open them.

@jstac what do you think? Consolidate our news-reporting-bot and have a hyper focus on lectures updates predominantly?

Here are the first two weeks of posts

This is what the latest news feed looks like on the main page now

Thanks @mmcky . a single weekly post plus other ad hoc posts (a new workshop, etc) sounds like a good model to me!
