[Feature] Transform floating window to preview window

[williamboman]

Hello! I personally prefer to send the contents of a floating window to a preview window, so that I can keep it open for a little while longer (and to get more screen real estate than a floating window). Do you think it'd make sense to include this an option in this plugin? I'd be happy to send a PR for it in that case. To give some idea how I'd implement it - I've currently accomplished this in my own config like so (this was prior to trying hover.nvim), it's a bit messy but it works.

Sounds good to me. This would be particularly useful for the Man provider.
