* Add constraint for MarkupSafe
MarkupSafe >= 2.0.0 requires Python >= 3.6.0. Add a constraint for older Python versions
and fix the `groupby_filter` test.
* Fix template_jinja2_latest test.
* patch filter decorators on newer Jinja2
* Jinja2 >= 3.0 renames several filter decorators used by Ansible itself, as well as by filters in collections. This patch ensures that the old names are usable within Ansible and by collections without warnings or errors.
* Ignore docs-build issues.
