Generate required fields for DABs (#3036)

## Changes
This PR generates patterns for fields to perform required validation on.
These patterns will be automatically updated every time we bump the SDK
and run genkit.

## Why
These generated fields are used in
#3044 to perform the actual
validation. See: bundle/config/validate/required.go in that PR.
