Change or remove news feed

[amongonz]

Out of the 5 "news" entries visible in fsharp.org as of writing, 3 are articles about AI, unrelated to F#, and another just mentions F# in passing. Apparently the feed is taken from fpish's F# blog aggregator, but at least half the posts there are completely unrelated to F# nowadays.

I suggest changing the feed to a higher quality source of F# news or removing it altogether.

If you feel like making a PR to remove it, I think we'd all be open to that.

Seems the feed was removed in #956, so this can be closed now.
