Unified clipboard between Neovim and Windows WSL2

Install win32yank.exe

SHELL
$ curl -sLo/tmp/win32yank.zip https://github.com/equalsraf/win32yank/releases/download/v0.0.4/win32yank-x64.zip
$ unzip -p /tmp/win32yank.zip win32yank.exe > /tmp/win32yank.exe
$ chmod +x /tmp/win32yank.exe
$ sudo mv /tmp/win32yank.exe /usr/local/bin/

Remember to restart shell, to cache binary. I experienced not being able to access it straight after download and move.

Configure Neovim
