`DOMDocument::loadHTML` will parse HTML documents as ISO-8859-1 if there is no `meta[charset]` tag. This means that UTF-8-encoded HTML fragments such as those coming from JSON-LD `articleBody` field would be parsed with incorrect encoding.
In f14428e4c0, we tried to resolve it by putting `meta[charset]` tag at the start of the HTML fragment. Unfortunately, it turns out that causes parser to auto-insert a `html` element, losing the attributes of the original `html` tag.
Let’s try to insert the `meta[charset]` tag into the proper place in the HTML document.
We do not need to use the same trick with `JSLikeHTMLElement::__set`.
That expects smaller HTML fragments, not `html` documents, so creating `html` and `head` elements will not be a problem.
Once we bump minimum PHP version, we will get newer PHP-CS-Fixer,
which will try to apply this cleanups.
Also manually tweak anonymous functions so that they are cleanly formatted
once we switch to `fn` syntax.
Readability was previously removing (was trying to actually, see next
section) invisible nodes using a pattern from `unlikelyCandidates`. This
was quite hacky and was removed during a backport of logics from
mozilla/readability. There is still a need to remove them so here we
are. We still use a pattern but specifically against the style
attribute. We also remove nodes with the attribute `hidden`.
The clean feature of tidy actually replaces inline style attributes
with css classes thus preventing readability to detect invisible nodes,
see https://github.com/htacg/tidy-html5/blob/5.6.0/src/clean.c#L1488
We therefore set clean configuration to false.

This change backports several things from mozilla/readability:
- Add child score to all ancestors instead of the first parent only
- Check 5 top candidates and try to find alternative candidates within
ancestors, this can help to find a better parent and grab more content
- Reduce patterns from `unlikelyCandidates` to the one used by Mozilla
as ours tend to remove useful nodes
- Score headers (h2 to h6) by default in addition to div, p, td and
section

We append a new node when it isn't a `div` or `p` (like when it's an `article`) with the same id which generate a DOM error "DOMElement::setAttribute(): ID blabla already defined".
Most the time, they can be usefull.
At least, it'll be a link to something unrelated. But we won't lose a link inside the content.
Also, adding some extra space.
