[Linux][1.11.0] Blueprint does not start: "cannot find fix-path'"

[marcdumais-work]

Bug Description:

Blueprint v1.11.0 does not start. I get the same error with the .Appimage or the Debian installer version:
$ /opt/TheiaBlueprint/theia-blueprint

A JavaScript error occurred in the main process
Uncaught Exception:
Error: Cannot find module 'fix-path'
Require stack:
- /opt/TheiaBlueprint/resources/app/src-gen/frontend/electron-main.js
- /opt/TheiaBlueprint/resources/app/scripts/theia-electron-main.js

Steps to Reproduce:

1. download .deb or AppImage from https://download.eclipse.org/theia/1.11.0/linux/)
2. chmod +x and start .AppImage or for .deb start: /opt/TheiaBlueprint/theia-blueprint

Additional Information

• Operating System: Ubuntu 20.04
• Theia Version: 1.11

I have not tested the Windows or MacOS packages, so I assume the issue may be Linux-specific.

I know this is likely fixed now, but fyi same error with v1.11.0 on macOS
