Unable to get tigervnc when building the image

[ericksantillanp]

Describe the bug: By building the image from scratch it seems that this package is no longer in https://dl.bintray.com/tigervnc/stable/tigervnc-1.11.0.x86_64.tar.gz :

https://github.com/ml-tooling/ml-workspace/blob/91a3cea2e1597474bf71707b5636d4c640898e67/Dockerfile#L430

Here are the logs after a docker build .

Steps to reproduce the issue:

docker build .

Technical details:

• Workspace version :
• Docker version :
• Host Machine OS (Windows/Linux/Mac):
• Command used to start the workspace :
• Browser (Chrome/Firefox/Safari):

Possible Fix:

I think this is the new place: https://sourceforge.net/projects/tigervnc/files/stable/1.11.0/tigervnc-1.11.0.x86_64.tar.gz/download

Hey @ericksantillanp, thanks for the update! In case the newer vnc version does not start in the workspace, have a look at this commit (in that branch we are working on a version for Ubuntu 20.04).
