[rollup-plugin-html] '@web/rollup-plugin-html' does not provide an export named 'default'

[CxRes]

This is either a documentation issue or an API issue depending on author intent:

The following example from the documentation fails:

import html from '@web/rollup-plugin-html';

with the error:

SyntaxError: The requested module '@web/rollup-plugin-html' does not provide an export named 'default'

The library provides a named export called rollupPluginHTML. Either documentation needs to reflect this or a default export should be provided.
