chore(.vscode): add remaining packages to VSCode workspace (#20570)

## Context
This PR extends the multi-root VSCode workspace configuration introduced
in #2937 by adding the remaining packages from the `packages/*`
directories to the `twenty.code-workspace` folders array.

## Problem
Previously, some packages were not added to the multi-root workspace
configuration. As a result, when opening the repository as a vscode
workspace, those packages were hidden from the VSCode Explorer because
they were not part of the configured workspace folders.

## Benefits

- Prevents packages from being hidden when the repository is opened as a
vscode workspace.
- Improves consistency and navigation across the monorepo workspace
experience.
