Mount points in DS Projects are misleading

Description of problem:

In DS Projects, there are different mount points indicated for the different volumes that are accessible. In this example, the mount path are listed as "/" and "/data":

When you are inside Jupyter, those mount paths, if taken "as displayed" are not working:

This is "normal", because the integrated browser in Jupyter is relative to the directory where it is started from unless configured otherwise.

This can be of course very confusing for the user. Moreover, that means that supplementary volumes cannot be mounted elsewhere than under /opt/app-root/src. There may be use cases where you want a volume to be mounted elsewhere, for shared binaries or libraries for example.

Actual results:

Indicated mount path is for example "/data", but it's not true, it's "/opt/app-root/src/data". In JupyterLab, when you right-click on the folder and "copy path", what you will have in the clipboard is not "/data" but "data" because JupyterLab knows that what it displays is a relative path.

Expected results:

To avoid misunderstandings, the dashboard should indicate the full mount point as well as the relative path it will appear under in the JupyterLab browser. This should also be clear in the configuration panels.
