User Guide: Html tags description

in user guide many examples refer to html tags in strings as:
https://pytest-html.readthedocs.io/en/latest/user_guide.html#additional-summary-information

def pytest_html_results_summary(prefix, summary, postfix):
    prefix.extend(["<p>foo: bar</p>"])

by doing that, the <p> tag as well as other html tags (e.g. <div> or <h2>) are recognized as text.

The correct example would be to use py.xml package:

from py.xml import html

def pytest_html_results_summary(prefix, summary, postfix):
    prefix.extend([html.p("foo: bar")])

Another useful example would be the one to add a log to the Results Summary:

from py.xml import html

def pytest_html_results_summary(prefix, summary, postfix):
    postfix.extend([html.div("My additional log", class_='log')])

the User Guide shall be updated according to the correct html way to add information to the report sections.

Open the User Guide at the Additional Summary Information section linked in the issue and review its HTML examples. Update the examples to use py.xml.html elements, including the results summary and additional log examples; done means the guide shows the corrected HTML construction.
