Use node20_1 for sleepCommand when running container

[DenisRumyantsev]

Description: there is no Node (version 6) in the Alternate Agent versions, and it will be removed from the vsts-agent version soon, so we need to use Node20_1 when starting Docker containers.

Docker command —

docker create --name <name> --label <label> --network <network>
-v "_work":"C:\__w"
-v "_work\_tasks":"C:\__w\_tasks"
-v "_work\_tool":"C:\__t"
-v "externals":"C:\__a\externals"
mcr.microsoft.com/windows/servercore:ltsc2022
"C:\__a\externals\node20_1\bin\node.exe"
-e "setInterval(function(){}, 24 * 60 * 60 * 1000);"
