Update for new package name

BREAKING: Change the package name from `@codemirror/example-setup` to
just `codemirror`.

BREAKING: The package no longer exports `EditorState` (since that is
no longer necessary to set up a basic editor).

FEATURE: The new `minimalSetup` export provides a minimal set of
editor extensions.
