Update up-next icon to be 24dp

[mchowning]

Description

When I updated the up next icon to be more centered, the svg's width and height were reduced, and I didn't realize this would reduce the icon's size on the podcast settings screen. This increases the size of the new icon to be the same as the old icon.

Warning
Because this is a regression from 7.37, I'm targeting the release/7.38 branch. I don't think we need to release a new beta with this though, and it can just go out with the next beta or the actual prod release.
