feat: resize window on nvim resize (#117)

Browse Source 
Fixes #116 


https://github.com/kdheepak/lazygit.nvim/assets/167217/729c203a-c873-45c8-8346-cd7266d9eb2f

The `defer` is a bit of a hack, but otherwise the new size doesn't get
enough time to be properly registered. It still sometimes messes up and
positions itself slightly off sometimes if I try to do it several times
fast, so maybe the delay needs to be adjusted, some debounce added, or
we might want to find a different method for ensuring the window has the
correct size.
