[FIX] web_editor: remove dead code in html_field

The template `web_editor.assets_edit_html_field` was not used nor
required anymore. The files under that bundle were already included
in the backend.

The template under the key `cssEditAssetId` in html_field.js is in fact
loaded in wysiwyg_iframe.js through the option iframeCssAssets.

Moreover, the line `await getBundle` was doing nothing meaningful as
the bundle assets would not be loaded after being fetched.
