Subject: [PATCH] Bump html-pipeline to 2.8.4

In 2.8.3, it was possible to modify a constant without knowing it, which
led to a major performance regression (https://gitlab.com/gitlab-org/gitlab-ce/issues/49409).
Now attempting to modify the HTML::Pipeline::SanitizationFilter.WHITELIST will result in
"can't modify frozen Hash".

See https://github.com/jch/html-pipeline/pull/299.
