Migrate from rollup-plugin-babel to @rollup/plugin-babel

BREAKING: requires Node 10+

- was getting a warning on install:
  - "npm WARN deprecated rollup-plugin-babel@4.4.0: This package has been deprecated and is no longer maintained. Please use @rollup/plugin-babel."

- c.f. https://github.com/rollup/plugins/blob/master/packages/babel/CHANGELOG.md#breaking-changes
  - `babelPlugin.custom` is now a separate export,
    `createBabelInputPluginFactory`
  - `babelHelpers: 'bundled'` was added
    - this is the default and backward-compatible with 4.x, but they
      recommended explicitly configuring it as such

- c.f. https://github.com/rollup/plugins/blob/master/packages/babel/CHANGELOG.md#v510
  - typings have been added to the package directly, no need to declare
    module to workaround lack of typings anymore

- remove old commented out line referring to rollup-plugin-babel as well
