Update Python versions, pin Ubuntu and service database images

[saaj]

Summary

• Pin CI database service images
• Pin Ubuntu version to 22.04
• Tidy up supported Python versions: remove EOL 3.6 and 3.7, add 3.11, bump PyPy, remove Pyston
• Target 0.10.0 release

Motivation

On #255 CI broken because one of service containers (mariadb) failed to start. Exact reason
isn't clear from the messages.

   PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
   To do so, start the server, then issue the following command:
   
   '/usr/bin/mariadb-secure-installation'
   
   which will also give you the option of removing the test
   databases and anonymous user created by default.  This is
   strongly recommended for production servers.

  Error: Failed to initialize container mariadb

But because tests databases aren't pinned that likely has happened due to the image update.
