Always set LAZYGIT_COLUMNS

Browse source 
The env var was previously set only on Windows, where the no-op pty
stub was just running the command without a pty and needed to expose
the width to pager scripts another way. With ConPTY coming to Windows
the rationale disappears there, but the env var is documented in
docs/Custom_Pagers.md for pager scripts that can't query the terminal
width directly. Set it on every platform so those scripts remain
portable, regardless of whether a pty is in play.
