Intermittent error while reading clipboard on Linux

[caleb-allen]

After enabling the clipboard feature using VimBindings.Config.system_clipboard!(true), I occasionally get an error while trying to paste the clipboard with p.

I'm running wayland with sway 1.8.1, and the clipboard appears to be attempting to read from xclip (instead of wl-paste).

This probably needs a PR to julia itself, but I want to record it here anyways.

Closing this since it is an issue with InteractiveUtils, not VimBindings
