fix: removing patches for bedrock resources (#1760)

1. The issue building source model db, due to error importing "oneOf"
union type, was fixed by #1666.
2. The patches prevent the CDK L1 to be updated automatically.

After this fix, the modifications in Bedrock resources will
automatically be applied to the CDK L1 constructs.

This should address the concern from this comment:
