Fix path formatting in generating VSCode settings for Windows compatibility

[XingxinHE]

Description

Hi @sheikh-nv , @vick-yu , I'm reporting an issue I encountered when using python -m isaacsim --generate-vscode-settings to create the VS Code configuration, particularly on Windows. Following the Visual Studio Code Support, the generated .vscode/settings.json contains unescaped backslashes in the python.defaultInterpreterPath and python.analysis.extraPaths entries.

The root cause is

IsaacSim/source/python_packages/isaacsim/__main__.py

Line 123 in 07d8dd4

template = template.replace("PYTHON.DEFAULTINTERPRETERPATH", sys.executable)

and

IsaacSim/source/python_packages/isaacsim/__main__.py

Line 128 in 07d8dd4

template = template.replace("PYTHON.ANALYSIS.EXTRAPATHS", content)
