Add support for Open edX Redwood release

* Update the import statement for xblock-utils

  The `xblock-utils` library has been deprecated as a separate package;
  the `utils` library has been moved into the `XBlock` and should now
  be imported from `xblock.utils` instead.
  (openedx/XBlock#675)

* Upgrade to XBlock 2
  Remove the use of deprecated `xblock.fragment` and direct
  id_generator parameters. 9openedx/XBlock#680)

* Add Python 3.11 to test matrix; Drop Python 3.8 from test matrix

* Add a version compatibility matrix to the README

Fixes: citynetwork#38
