Add tip box: output to clipboard via .once |pbcopy

[tbbuck]

Hi there!

I stumbled across this mega useful method for quickly getting output rows from duckdb by calling .once |pbcopy - means that I can paste into other tools without having to faff around with the mouse selecting text and so on. While I'm pretty sure there's a similar method for Linux, my knowledge is out of date - same for Windows.

Thought it's worth highlighting for other people as it's one of those small little things that turns out to be awesome for day-to-day work. My use case is testing GeoJSON + WKT outputs on maps and matching.

Thanks
Tom.

Hi, this is great, thanks! I think somesthing similar must definitely work for Linux using xsel or xclip. I'll leave that for future work and merge this now.
