Adjust post update hooks based on the current version of the module

Attached patch must be applied to the dev branch of section library.

Found out something super obscure:
"Turns out you shouldn't set data_table in the entity type annotation if translatable is FALSE. Otherwise views associates all of the fields with the data_table, but data_table is never associated with base_table due to translations being disabled."

Removing the data_table property from the entity allows custom fields to appear as options in section library views.

Updated patch attached.

Hi,

Thanks @jastraat for your work in this.

I confirm:
- I no more see the error message when saving the view
- I now have access to the additional fields set through the UI

Thank you for testing!

Updating this to the relevant major version.
