Two obsolete usage in /en/BashOnWindows.md

[yihuajack]

1. In Section "Preferred way to run WSL {#connector}", the task parameters

/dir %CD% /icon "%USERPROFILE%\AppData\Local\lxss\bash.ico"

is obsolete. WSL no longer put icon file there.
2. In Section "Get 24-bit colors working in ConEmu {#wslbridge}" Subsection "WSLBridge installation and Task contents {#wslbridge-task}", the task parameters (icon)

-icon "%ProgramW6432%\WindowsApps\CanonicalGroupLimited.UbuntuonWindows_1604.2017.922.0_x64__79rhkp1fndgsc\images\icon.ico"

is also obsolete. WSL no longer put icon file there. Besides, it is only for Ubuntu 16.04.

In addition, I suggest add an alternative configuration

wsl.exe

according to LostInBrittany's solution and

set "PATH=%ConEmuBaseDirShort%\wsl;%PATH%" & "%ConEmuBaseDirShort%\conemu-cyg-64.exe" "%ConEmuBaseDirShort%\wsl\wslbridge2.exe" -cur_console:pm:/mnt -eConEmuBuild -eConEmuPID -eConEmuServerPID -l

according to JakubJachym's solution in repository Maximus5/ConEmu Issue #1930.
