"The editor just crashed" on fresh install

wagtail==2.11.3
wagtail-footnotes==0.4.1
Django==3.1.4

When I click on the "Fn" button, I get:

Error: Minified React error #130; visit https://reactjs.org/docs/error-decoder.html?invariant=130&args[]=undefined&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

Hi, the problem can be solved by removing:

@hooks.register("insert_editor_js")
def editor_js():
    js_files = ['wagtailadmin/js/draftail.js', 'footnotes/js/footnotes.js']
    js_includes = format_html_join('\n', '<script src="{0}"></script>',
        ((static(filename),) for filename in js_files)
    )
    return js_includes

from wagtail_hooks.py and adding: js = ['wagtailadmin/js/draftail.js', 'footnotes/js/footnotes.js'] into:

features.register_editor_plugin(
        "draftail",
        feature_name,
        draftail_features.EntityFeature(
            control,
            js = ['wagtailadmin/js/draftail.js', 'footnotes/js/footnotes.js']
        ),
    )

within the register_footnotes_feature(features) function.

I'm not sure why registring of js files is not working. It seems to be a problem since wagtail 2.11.

Thanks, @alexgorji for spotting that, I have made this change and included it in the latest release 0.5.0
(Apologies for taking a while to get to this, I've been quite busy the past few months)
