Improve VSCode performance by removing jsconfig.json

[mehmoodak]

Proposed Changes

Improve VS Code performance by removing jsconfig.json file.

Similar action has been taken in Gutenberg codebase to improve performance (WordPress/gutenberg#68347)

Why are these changes being made?

If you open the project in VS Code and open few files, you will see this warning:

Removing the file also helps to avoid conflicts between two config files.

Testing Instructions

1. On trunk, open the project in VS Code
2. Open following files and most probably you will see the "Configure Excludes" message.
   • client/blocks/reader-author-link/index.tsx
   • apps/blaze-dashboard/src/components/layout.jsx
   • client/devdocs/design/wordpress-components-gallery/snackbar.tsx
3. Confirm that you see that above mentioned warning.
4. Now, on this branch, reload VS Code Cmd/Ctrl + Shift + P > Developer: Reload Window
5. Open the same files
6. Confirm that there is no warning
