chores: update dependencies

1. Updated husky to 7.0.4 which meant adding the .husky folder with
   the lint-staged task as a pre-commit step.

2. Updated TypeScript which meant the error object inside catch now has
   type unknown and needs casting to be used as custom type.

3. Updated Jest which meant that `async (done)` is no longer allowed,
   removed all the `done`'s. This is alright because we do assertion
   checks.

4. Updated GitHub workflow to drop node 10 support and add support for
   node 16.
