Fix script execution for Linux VSCode development

This commit improves the VSCode configuration script for Linux-based
development environments.

It fixes a script execution failure in the deskto version during
development when using VSCode installed via Snap or Flatpak. It resolves
the following error encountered during script execution in development
mode (`npm run electron:dev`):

`symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0:
 undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE`

Changes:

- Add a setting in VSCode configuration script to workaround script
  execution errors in sandboxed VSCode installations on Linux (see
  see microsoft/vscode#179274).
- Migrate the configuration script to Python for cross-platform
  compatibility and simplicity.
- Refactor the script for better extensibility.
- Automate installation of recommended VSCode extensions.
- Recommend VSCode Pylint extension for Python linting.
- Standardize Python development settings in `.editorconfig`.
