Fix 2022_v1.0 and update docs for Future Upgrades run
These are the tiny changes essential for Future Upgrades.
This merge request changes the 2022
datatype path from run3/2022_v1.0
to run3/trunk
. Necessary because Detector!461 (merged) deletes 2022_v1.0
.
Also updates documentation for future upgrade devs.
