[StateAccumulator] Remove v2 disable functionality from node config (M…

…ystenLabs#18786)

## Description 

Before removing v1, we need to ensure that no one has v2 force disabled,
as it would otherwise lead to a fork during upgrade due to forcing v2 to
be enabled mid-epoch.

## Test plan 

How did you test the new or updated feature?
