disables format on save and prettier for typescript files on backend

Disables format on save and prettier for typescript files. duplicates the same settings that are already in place for the frontend Javascript files for the the backend TypeScript files.

I don't use vscode, eslint on save is built into JetBrains IDE's. But this seems like a personal decision, why would turning that off be the default?

This file is specific for VSCode settings. eslint on save is still active. This disables the prettier extension save on format. When you save the file, it will still format according to the eslint rules. This PR is just duplicating the setting that are already in place for the front end javascript files, and applying them to the typescript files.
