Fix: Tests broken by Python 3.13.6+ html.parser changes - Exclude title elements from text wrapping

[natsukium]

Thank you for this great project! I tried to use ReadabiliPy with Python 3.13.7 and found that tests were failing, so I investigated the cause and implemented a fix.

Context

Python 3.13.6+ introduced stricter HTML5 compliance in html.parser which causes our tests to fail.

Problem

• The wrap_bare_text function wraps ALL bare text in <p> tags, including text inside <title> elements
• This creates invalid HTML: <title><p>Text</p></title>
• Python 3.13.6+ with stricter HTML parsing serializes this as <title>&lt;p&gt;Text&lt;/p&gt;</title> (escaping the invalid nested tags)
• Tests fail because expected output has <title><p>Text</p></title> but actual has escaped version

Solution

• Skip wrapping text in <title> elements as they can only contain text per HTML spec
• According to MDN, <title> elements are only allowed "Text that is not inter-element whitespace"
• Reference: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/title#technical_summary
