Update practicemode.sp

Update map list to reflect active duty

[splewis]

I would prefer this list to:

• contain all the recently used competitive maps, not just the current ones, to reduce how often users feel the need to adjust the default maplist

• be kept in sync with the default config: https://github.com/splewis/csgo-practice-mode/blob/ebadb0383a00b28ad58d42de134a333d4300f39e/configs/practicemode.cfg#L15-L24
