Character count attributes namespace

[matthew-shaw]

Sorry to jump in (hello from the NHS port 👋)

We spotted another issue where a namespace is necessary:

govuk-frontend-jinja/govuk_frontend_jinja/templates/components/character-count/macro.html

Lines 92 to 94 in 4584974

	{%- for name, value in params.formGroup.attributes if params.formGroup %}
	{% set attributesHtml = attributesHtml ~ " " ~ name | escape ~ '="' ~ value | escape ~ '"' %}
	{% endfor -%}

Using the same approach as the govukAttributes() macro that should be:

{%- for name, value in (params.formGroup.attributes.items() if params.formGroup.attributes else {}.items()) %}
  {% set ns.attributesHtml = '{} {}="{}"'.format(ns.attributesHtml, name | escape, value | escape) %}
{% endfor -%}

For our NHS fix (mostly the same) you can see NHSDigital/nhsuk-frontend-jinja@903bcaf
