Format files

[safwansamsudeen]

1. Formats existing files
2. Fixes (and renames) formatting command in package.json.
3. Adds pre commit CI to format the files and error out when devs try to commit unformatted work.

Example with a "wrong" commit:

You should probably ignore blame for the mass format commit
