Eslint (#998)

## Description:

Enable a few eslint rules:
- `@typescript-eslint/no-empty-object-type`
- `@typescript-eslint/no-require-imports`
- `no-useless-escape`

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors
