[issue44737] Mapping from to collections.abc

[Du]

New submission from Du <491609917 at qq.com>:

When using Sanic, referencing Mapping in collections in SANic-Jinja2 brings ImportError: Cannot import name 'Mapping' from 'collections'. When you use Mapping, shouldn't you call from collections.abc?
