package.json has an invalid type property

[jlaine]

While attempting to build a project which uses tinymce-i18n with esbuild I encountered the following warning:

    node_modules/tinymce-i18n/package.json:11:10:
      11 │   "type": "library",
         ╵           ~~~~~~~~~

  The "type" field must be set to either "commonjs" or "module".

The NodeJS documentation confirms that "library" is not a valid value for this field:

https://nodejs.org/api/packages.html#type

AFAICT, the most straightforward fix is to remove the "type" field, which should retain the current behaviour: this package is a legacy commonjs module.
