Fixes for building .vsix file

[tonis2]

@pherrymason Let me know if you find any issues with below changes

I created some fixes to the extensions to make it work on my Linux machine.

Also edited the pop-up dialog message a bit, and used below messages, In my opinion it explains better what the actions do.

 "Download LSP binary",
 "Specify LSP binary path",
