RemoteCommand is executed with `powershell` on linux machine (incorrect platform detection)

Since today, I use the to run a custom .bashrc for a specific ssh connection to setup a environment for my remote vsc running on an Ubuntu 20.04:

Host vsc-v100-alpaka
ForwardAgent no
Hostname ***
ServerAliveInterval 15
ServerAliveCountMax 4
User ***
ForwardX11 yes
Compression yes
IdentityFile ~/.ssh/***
IdentitiesOnly yes
RemoteCommand /bin/bash --rcfile ~/workspace/caravan/alpaka/.vscode/env_init.sh -i
Proxycommand sh -c "ssh loginNode1 -W %h:%p || exec ssh loginNode2 -W %h:%p"

Since today, it is not working anymore, because vsc detects the system as Windows and tries to execute the powershell. I already tried the option remote.SSH.remotePlatform without success:

"remote.SSH.remotePlatform": {
        "vsc-v100-alpaka": "linux",
        "vsc-v100-vikunja": "linux",
        "v100": "linux"
    },

If I disable useLocalServer, the remote system is correct detected as Linux but than enableRemoteCommand is not working anymore.

Reproduce the SSH connection with remote.SSH.useLocalServer and remote.SSH.enableRemoteCommand enabled, then compare it with the useLocalServer-disabled behavior. Inspect the Remote-SSH resolver path represented by out/extension.js and the logged platform detection; done means the Ubuntu host is identified as Linux and RemoteCommand works without invoking powershell.
