Eslint stylistic improvements

[ann-kilzer]

Part of #51

What changed 🧐

• Add some new eslint rules to remove extra whitespace within and in line ends
• Add a rule to prevent any type
• switch from stylistic/ts to the newer stylistic which consolidates all the js ts jsx rules into one package

How did you test it? 🧪

I tested manually by adding code that broke each rule, and then running npm run lint to ensure that the error is caught

1. Add extra spaces in the middle of a line
2. Add extra spaces at the end of a line
3. Define a variable with any type:

let foo: any = 5
