It's a fine example of twisty English that's been compacted down for
length instead of clarity; it took me a couple of passes to decide this
is probably what it means:
If you check the box, the installation process of pgAgent will not load
certain (any?) pgAgent scripts. These scripts are for pgAgent's own
internal use, when you upgrade Postgres itself using pg_upgrade.

It sounds like you probably want to leave this unchecked, based on "I
have a mild preference for treating 12 as a clean install without
migrating anything from 11".
