wsl2 很能吃内存，而且 Windows10 抢不过 wsl2

[systemcall]

电脑只有 16G 的内存，装了 wsl2 和使用 wsl2 的 docker-desktop
wsl2 里面编译点东西，有时候就会把内存占满，之后就连 wallpaper engine 都开始卡，chrome 和新 edge 也开始频繁的重载网页
关键是 wsl2 吃了的内存，程序不用了之后被 wsl2 用来当缓存了，win10 吃不到内存只能用页面文件撑着

Workaround: Create a %UserProfile%\.wslconfig file in Windows and use it to limit memory assigned to WSL2 VM.

Example
[wsl2]
memory=6GB
swap=0
localhostForwarding=true
This will still consume the entire 6GBs regardless of Linux memory usage, but at least it'll stop growing more than that.

Supported settings are documented here.
