Autoescape should be TRUE by default

[HongYang01]

I suggest this because I was new to python-docx and generating reports that contained < > & characters. At first, I was miserable; the report was generated successfully but was corrupted when opened in MS Word.

So, I hope the team could make the "Autoescape" to True by default.

        self,
        context: Dict[str, Any],
        jinja_env: Optional[Environment] = None,
        autoescape: bool = False
    ) -> None:
{...}
