Replace removeChild with remove (#213465)

* Replace removeChild with remove

This replaces most uses of `parent.removeChild(child)` with
`child.remove()`.

The two are almost equivalent. The only difference is that
`parent.removeChild(child)` throws if the given node is not a child of
the parent, whereas `child.remove()` never throws. There is no noticable
performance difference. The only reason to use `removeChild` is to
support Internet Explorer, but that’s no longer supported by Monaco
editor.

* Fix broken CSP hash

The script content changed, so the sha256 hash changed too.

* Update src/vs/editor/browser/config/charWidthReader.ts
