Fix recipe_check_obs to be aligned with DKRZ

[LisaBock]

Description

There are missing observations when testing the recipe for the release on DKRZ.

Changes in the recipe:

• AGCD: Tier 3 -> Tier 2 in the recipe

• AERONET: version -> '20240406'

• ERA5 rlus + rsus, 1hr+mon: commented out in the recipe as they are not available at DKRZ

• JRA-25: changed end date to 2007 (instead of 2013)

• Closes #3660

All data is found with the changes but the recipe is still not running successfully for me. @axel-lauer Could you test it as well?
