Incorporate settings.json file on vscode server workbench

[atheo89]

Related to: https://issues.redhat.com/browse/RHOAIENG-2312

Description

This PR enables passing the settings.json file located within local/share/code-server/User/ in vscode. This is done to utilize the defaultInterpreterPath setting, thereby facilitating the selection of the interpreter.

On the official documentation is mentioned the following:

Note: Changes to this setting made after an interpreter has been selected for a workspace will not be applied or considered by the Python extension. The Python extension doesn't automatically add or change this setting.

Therefore, in accordance with that, and since we have already pre-installed the Python extension, the user should specify the "/opt/app-root/bin/python3" interpreter at least once.

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work
