Blurbs: set autoescape in Jinja2 environment

[Laren-AWS]

Best practice is to set autoescape in your Jinja2 environment in render-blurbs.py:

from jinja2 import FileSystemLoader, select_autoescape

        env = Environment(
            autoescape=select_autoescape(enabled_extensions=('html', 'xml'), default_for_string=True),
            loader=FileSystemLoader(os.path.dirname(__file__)),
        )

Or similar, assuming this doesn't break anything.

Isn't autoescape set to True by default? Even so, I can't find the render-blurbs.py file, only a render.py file that uses this library in a best practice way (using default true setting).

Assigning back to Laren until he can clarify what the ask is here, because all of the examples of autoescape currently in our repo have it set to default true.

It's not True by default, that's the trouble--it should be but for some reason the creators didn't do it that way.

The file is here, you merged it 9 months ago: https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/.doc_gen/images/render-blurbs.py

If you don't need it, I say remove the whole thing.
