How can I Install Another Version Extension

[pollenjp]

• code-server version: 1.31.1-100
• OS Version: Ubuntu16.04
• Extension: all (example Vim)

Steps to Reproduce

1. I try to downgrade vim plugin to v1.0.8, but there is no selections without v1.1.0 when I click "Install Another Version..." (Fig1).

I want to downgrade vim because I am hitting #61 problem.

My local VSCode can choose another version (Fig2).

This behavior is seen in other extensions (like Python or C++). I don't know whether this is a bug or not because I am not familiar with VSCode.

I tried to install from VSIX, but got an error "Invalid tar header. Maybe the tar is corrupted or it needs to be gunzipped?"

example: vim-1.0.8.vsix

Related to #92 maybe?

Maybe

Manual installation of VSIXs should be fixed via #245.
