Configure devworkspace namespace with user name and email in gitconfig

[metlos]

Is your enhancement related to a problem? Please describe

Che server supports storing the user's name and email in the gitconfig mounted to the Che7 workspaces. This is currently not possible for devworkspaces because devworkspace operator doesn't support this.

Describe the solution you'd like

Once support for this lands in DWO, we should decide how to implement this in Che. We can either simply take the user name and email from the database record as we do now for che7 workspaces or we can take advantage of the che.eclipse.org/workspace-namespace-owner-uid that is required on che-targetted namespaces and draw the information from there directly.

Describe alternatives you've considered

No response

Additional context

There is an issue for implementing this on the DWO side: devfile/devworkspace-operator#694

We can either simply take the user name and email from the database record

my understanding that the vision is that database will cease to exist in the future releases, so probably this is not the best option to consider

@metlos another reason not to fall back on db - eclipse-che/che-docs#2159 (comment)
