Update formatting for .ts and .json files in apps/vscode/

[juliasilge]

This PR updates the formatting on .ts and .json to use the workspace settings, so we don't continue to have so much extraneous whitespace change in PRs like #589.

eep let us merge in the existing ones first!

Wait for #577 to be merged, before merging this one (I think #585 will be easy to resolve)

We should also see if we can set these

    "files.insertFinalNewline": true,
    "files.trimFinalNewlines": true,
    "files.trimTrailingWhitespace": true,

at the very least, trim trailing whitespace would be nice - but i dont know how to reapply it over the whole folder

This one is now ready for a review and to be merged. Here's to making things less painful moving forward! 🙌
