Evolution-Data-Server 3.20.6 fixes for Google OAuth2 handling

[Milan Crha <mcrha redhat com>]

        Hello,
I just released the evolution-data-server 3.20.6, which contains fixes
for handling of the Google OAuth2 tokens in the Calendar, both for the
accounts configured through GNOME Online Accounts and for the accounts
configured directly in the Evolution.

I'd like to ask the distribution maintainers whom ship the 3.20.x to
update to this released version, especially if they want their users to
get smoother Google calendar experience. There will be less (or close
to none) 'Daily Limit Exceeded' errors shown, if it's done.

These changes are already part of the 3.22.2 release.

More detailed explanation and the reason why you should do it can be
found here:

        Bye,
        Milan
