Ctrl/Cmd+Scroll to zoom

[atc3]

When scrolling up and down the page the plots will capture your cursor and zoom a plot instead of scrolling the page itself -- this could get annoying for a large page. There is a "safe haven" on the side to scroll but it's annoying to have to remember that.

I would suggest changing the default scroll option within plots to be Ctrl/Cmd+Scroll instead of just scroll. The current Cmd+Scroll bind warps the axes which I don't think most people will use anyways, and you could map that to Shift+Scroll if you wanted to. This proposed keybind configuration is already used on most pages with Map embeds

I think this would reduce the discoverability of the zoom feature a lot. I agree that it's annoying that scroll is overloaded, but I don't want to add a hotkey for it. We could do the opposite, where a hotkey makes scroll always scroll the page?
