Can't install linux-x64 extension on WSL

[swatDong]

Type: Bug

I have an extension on different platforms (linux-x64 and universal), but when using VSCode connecting to WSL, it installs the universal one instead of the linux-x64 one.

Here's my extension for test adminalexwang2048.helloworld-sample-adminalexwang2048

I tried different versions with VSCode stable and insider builds, the results look weird. My extension has:

• 0.0.2 (stable) - linux-x64
• 0.0.2 (stable) - universal
• 0.0.3 (pre-release) - linux-x64
• 0.0.3 (pre-release) - universal

And when installing in VSCode / Insiders, the behaviors are:

• Use VSCode stable (1.100.2) connecting to WSL, install 0.0.2 (stable), it actually installs 0.0.2 (stable) - universal
• Use VSCode stable (1.100.2) connecting to WSL, install 0.0.3 (pre-release), it actually installs 0.0.3 (pre-release) - linux-x64
• Use VSCode insiders (1.101.0-insider) connecting to WSL, install 0.0.2 (stable), it actually installs 0.0.2 (stable) - universal
• Use VSCode insiders (1.101.0-insider) connecting to WSL, install 0.0.3 (pre-release), it actually installs 0.0.3 (pre-release) - universal

I expect it should always install the linux-x64 VSIX.
