docs(jinja): show a safe filter example in get_filters docstring

The get_filters docstring demonstrated building a LIKE clause by hand-escaping
the value with replace("'", "''"). That pattern is incomplete and easy to
misuse. Remove it from the example, keep the where_in-based IN example, and add
a warning against hand-escaping filter values into SQL.
