Add new structured content features: lists and the HTML `lang` attribute (#2129)

* Add support for structured content lists and `list-style-type` style

A full list of supported style types is documented here:
https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-type

There's nothing in this code preventing a term bank from assigning,
for example, a `list-style-type` style to a `div` element, but it
doesn't seem like browsers will complain about things like that.

* Add support for `lang` attribute in structured content

Support added for the following node types:

"ruby", "rt", "rp", "table", "thead", "tbody", "tfoot", "tr", "td",
"th", "span", "div", "ol", "ul", "li", "a"

I couldn't get it to work for the alt-hover text on "img" tags.

Tests are included in the file
"test/data/dictionaries/valid-dictionary/term_bank_1.json"

* Add styles for structured content lists

* Add override rules for new structured-content list styles
