Remove linting from pre-commit githook
Remove linting from pre-commit githook

These are taking a long time and the test
suite/ci is really the place for linting
and these linters are run as part of that now.

Having them in the githook:

1. means they run on every commit and amend

2. they take 12+ seconds each time
  ```
  Linting JavaScript files...
  yarn run v1.22.10
  $ standard
  ✨  Done in 1.59s.

  Linting SCSS files...
  yarn run v1.22.10
  $ stylelint **/*.scss
  ✨  Done in 12.12s.
  ```

3. it does not matter if lint errors are committed and pushed
   to github as they are caught by the CI anyway now.

4. most commits, for most devs, don't touch css/javascript
