Bumps climate-ref to 0.20.2, which pages series and scalar values through the (execution_id, type) id subquery instead of reading every value of that type (Climate-REF/climate-ref#1036).

This fixes the slow Cloud radiative effects series chart. On a copy of the staging database the lwcre zonal mean query took about 60s on fressnapf and now takes 0.01s. Locally it dropped from 4.6s to 0.02s.

There are no migrations between 0.20.1 and 0.20.2, so the fixture database is unchanged.

Summary by CodeRabbit

• Improvements
  • Series values load faster in the diagnostic explorer, including in Cloud radiative effects charts.
  • This makes chart data quicker to view when exploring diagnostic results. The improvement applies to loading series values across the explorer, with Cloud radiative effects charts included.
